Abstract :
This paper presents the control strategy and the experimental results of a high voltage gain converter with soft-switching cell. The PID compensator is digitally implemented using a PIC 16F877 microcontroller, which guarantees the regulation of the output voltage, instead of load variations. Low switching stress, ZCS operation for auxiliary switches and ZVS for main switches, and high efficiency are expected. Theoretical analysis, operation principle and topology details are presented and validated through experimental results.
