Abstract :
A fourth order PWM DC/DC or AC/DC converter is treated and a survey of important data (maximum voltage and current ratings for the elements, RMS values for the semiconductor devices and a rough approximation of the losses) of the circuit is given. Furthermore, a converter model including the losses based on duty ratio averaging is established. Due to the bidirectionality of the converter, continuous inductor current mode always occurs. Simulation and measurement results are given.
