Abstract: With fast advances in VLSI technology, smaller and more powerful digital systems are available. These systems require power supply with higher power density, high voltage profile and high efficiency. PWM topologies have been widely used for these applications. Unfortunately, hold up time requirement put huge penalties on performance of these topologies. Also high switching losses limit the power density achievable for these topologies. To achieve high power density and high efficiency simultaneously, resonant converter topologies are used. Nowadays a lot of work concerning the resonant converters is going on. Resonant converters utilize soft switching technology. In soft switching technology, switching done at the zero crossing of either current or voltage by using resonant circuit. This dissertation work presents the simulation and voltage gain variation with respect to switching frequency of various DC-DC converters with zero current switching and Zero Voltage Switching. It is also discusses the closed loop control of ZCS resonant DC-DC converter using PID and FUZZY Controllers with an objective to include rejection of input supply, variation in reference voltage and load transients. Hardware implementation of Zero Voltage Switching Resonant Buck Converter is also presented.
