This book was released on 2012-04 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a novel soft-switching of boost converter by using ARCP method, which realizes the zero-current switching(ZCS) of the main and auxiliary switches and possesses the small power auxiliary circuit and full PWM capability. In the ZCS, the auxiliary switch is turned-on before the main switch is turned-on, the power circuit relies on the addition of an auxiliary switch, diode and inductor circuit to commutate the inductive load current from a main diode to an active device enabling a zero current turn-on of the main device. This book addresses the optimum selection of the auxiliary and main inductor control parameters for the boost converter with soft switching technique; the auxiliary inductor parameter is derived based on a minimization of the losses for both main and auxiliary switches.

Download or read book Auxiliary Circuit assisted Soft Switching Techniques and Their Application to Power Converters written by Ranganathan Gurunathan and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need to incorporate significant improvements in power supplies is driven by customer demands, industry requirements and regulatory standards. For reduction in size and weight, it is imperative to process the power at a higher switching frequency. High frequency processing of power requires soft switching techniques to reduce the switching losses. Many soft switching techniques are reported in the literature to enhance the high frequency operation of power supplies. This thesis proposes novel high frequency, auxiliary circuit assisted, (a) soft-switched boost converters and their application to DC-to- DC converters and AC-to-DC front-end power factor corrected converters; and (b) zero-voltage switching (ZVS) dc link DC-to-AC inverters. In auxiliary circuit assisted soft transition converters, the auxiliary circuit processes the power during switching transitions, creating a soft transition path. In most of the proposed converters in the literature, the auxiliary circuit suffers from severe switching losses and switching stress. Discontinuous current operation of the auxiliary circuit results in parasitic oscillations between the switch capacitance and the resonant inductors increasing the stress on the devices. A zero-current switching (ZCS) auxiliary circuit and ZVS auxiliary circuit are proposed in this thesis to achieve soft transitions for the main circuit. A ZCS auxiliary circuit assisted soft transition boost converter is proposed. Operating intervals of the proposed technique in various intervals of operation are analyzed. Design constraints and considerations are discussed. A 300 W dc-to-dc boost converter and a 600 W, ac-to-dc power factor correction front-end boost converter prototype models are built in the laboratory. The experimental results confirm the theory. The resonant inductor used in the auxiliary circuit is coupled weakly to the boost inductor. Although parasitic oscillations are reduced due to the coupling, they are not completely eliminated. Hence, RC snubbers are required to suppress the oscillations. A ZVS auxiliary circuit assisted soft transition boost converter is also presented. Operating intervals of the proposed converter in various intervals of operation are analyzed. As all the parasitic elements in the circuit are accounted, parasitic oscillations are eliminated. A 300 W dc-to-dc converter operating at 250 kHz is built in the laboratory to verify the theory. A modified gating scheme to utilize the soft switching auxiliary circuit in the main power processing is also proposed. A 600 W, 100 kHz, 380 V dc, operating with universal input line voltage, ac-to-dc power factor corrected (PFC) boost converter is built using the proposed technique with modified gating algorithm. Large signal analysis to analyze the soft switching characteristics of the proposed technique during load and input voltage transients is also presented. PSPICE simulation results are presented to verify the theory. The proposed converter maintains soft switching during load and input voltage transients. The proposed auxiliary network is also extended to a family of pulse width modulated (PWM) converters. A two-switch soft switching boost converter is derived from the proposed converter. By integrating the proposed auxiliary network with a full bridge inverter, a ZVS dc link voltage source inverter (VSI) is obtained. Operating intervals of the proposed inverter in various intervals of operation for the forward power flow and reverse power flow are presented. A modified unipolar switching scheme to achieve ZVS during reverse power flow is also presented. The voltage stress on the VSI is clamped to the dc bus voltage in the proposed converter. The conduction losses are reduced as compared to other soft switching converters in the literature. As the proposed technique requires synchronized PWM operation, sine-ramp modulated PWM signals are used. Experimental results from a 120 V, 60 Hz, 300 VA, single phase VSI switching at 50 kHz are presented to verify the theory.

Download or read book Modeling Design and Control of Advanced Soft switching Boost Converters for PV based Battery Charging Systems written by and published by . This book was released on 2019 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Photo Voltaic (PV) systems in battery charging applications has been on the rise for the past decade. A PV module generates direct current and relatively low voltage; this voltage needs to be increased and stabilized using a DC-DC converter before charging a battery load. Due to the intermittent nature of the PV system, the input voltage varies with respect to weather conditions; therefore, it is vital to control and adjust the output voltage. In this work, we first utilize a switch-mode DC-DC boost converter with a proposed feedback control for a solar battery charging system. A fixed frequency compensated voltage- mode controller is designed and implemented for a DC-DC boost converter operating in Continuous Conduction Mode (CCM). Secondly, we design a full-wave quasi resonant DC-DC boost converter, as a softswitching technique, to increase the efficiency of DC- DC converter by reducing the switching losses is proposed. To achieve the soft switching functionality for the DC-DC boost converter, and to regulate a stable output voltage, a frequency control technique is proposed in this work. The proposed control strategy justifies both frequency and the duty cycle of the Pulse Width Modulated (PWM) control signal, which in turn controls the switching of the converter's switches. Finally, an interleaved DC-DC quasi-resonant boost converter for PV based battery charging is proposed to increase the efficiency of the battery charger system by reducing the ripple across the battery load. The topology of the circuit implements a Maximum Power Point Tracking (MPPT) algorithm at a specified solar irradiation. The control technique proposes a solution to obtain maximum voltage using Perturb and Observation (PO) method, obtains a conversion ratio for the converter topology, and applies frequency modulation to regulate the output voltage in order to design a robust charger. Matlab Simscape toolbox is used to conduct the simulation studies evaluating the performance of the proposed circuit topologies and controllers for a PV-based battery charging system.

Download or read book A Zero Voltage Switching Boost Converter Using a Soft Switching Auxiliary Circuit with Reduced Conduction Losses written by Nikhil Jain and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern AC-DC power supplies utilize power factor correction in order to minimize the harmonics in the input current drawn from the utility. The Boost topology is the most popular topology for power factor correction today but it has some disadvantages like very high EMI due to reverse recovery of the boost diode and high switching losses caused by hard switching of the boost switch. Many variations of the original boost topology have been suggested to overcome these problems. The Zero Voltage Transition Boost converter is one such solution. In such a converter an auxiliary resonant circuit is employed which is activated only when the boost switch is turning on or off. This auxiliary circuit allows the boost switch to turn on and off under zero voltage conditions thus reducing the switching losses. However the auxiliary circuit might be very complex and conduction losses in it might offset the expected rise in efficiency. In this thesis a soft-switching boost power converter is proposed and analyzed. This converter reduces the EMI and increases the efficiency because the auxiliary circuit is itself soft-switching and has low conduction losses due to creative placement of the resonant capacitors. Characteristic curves are generated for the proposed converter which not only give valuable insight on the behavior of the converter but also aid in designing the converter. The feasibility of the proposed converter is examined by means of results obtained from an experimental prototype.
