Abstract :
A fourth order PWM DC/DC converter with the possibility of bipolar output voltage is treated and a survey over 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, always continuous inductor current mode occurs. Simulation and measurement results are given.
