Abstract

This project is mainly about the study of resonant frequency in a converter system. The inverter circuit is also considered as a type of resonant converter. Inverter circuit goes through inversion process where inverter has additional stage that is the resonant stage where the DC signal is converted to high-frequency AC signal. The main objective of this project is to analyze the effect of resonant frequency greater than switching frequency (fr > fs) when this condition is varied. A switching frequency of 20 kHz is generated through voltage pulses in a full bridge RCL inverter circuit. The condition of the circuit is monitored when the resonant frequency of the circuit being varied through simulation using PSPICE. The simulation results will be analyzed based on the performance of current and voltage in the circuit. There are four different resonant frequencies used for comparison purpose. The results are analyzed and effects of resonant frequency higher than switching frequency will be clarified according to the circuit performance and the applications. The best condition varied through the simulation analysis is when the resonant frequency is 50 kHz. High resonant frequency contributes to reducing switching loss.
