Abstract :
The analysis and design of a zero voltage switching (ZVS) full bridge DC/DC converter control is discussed in this paper. The power converter is used to regulate the output dc voltage. With this objective, the control strategy presented here is designed based in the equations that describe the output current and output voltage dynamics. The proposed controller employs a dual-loop scheme implemented with two proportional-integral blocks. The performance of the controller is verified through several simulations, showing that the voltage at the dc-link is regulated to the desired reference value ensuring a correct operation of the selected topology.
