Minimum Switching Frequency Maximum Boost Control

A high-gain DC-DC system is implemented based on a switched condenser between the DC source and the inverter bridge (PWM) strategy related to the Interrupted CC voltage developed in this project with the Diode-back boost voltage inverter (VSI) amplificator. This project is a multiplication project. A new PWM strategy is proposed in this article to maximize voltage gain and increase efficiency. Interconnecting the voltage within a time-frame (Ts) of the three-phase line that controls the front boost circuit equal to the instantaneous maximum value. The equivalent switching frequency can be reduced to 1/3f(f=one/ts) within the electric converter bridge. Simulations and experiments analyse and check the functional principle and the structure of the controller.
