Abstract—In order to improve the modulation strategy of zero-voltage zero-current transition boost converter, an improved modulation strategy was put forward in this paper. The main switch can only achieve zero-current turn-on under traditional modulation strategy. However, the change to the turn-on time of main switch can make the main switch achieve zero-voltage zero-current turn-on, and the change to the turn-off time of auxiliary switch can realize the zero-voltage zero-current turn-off of auxiliary switch in advance as well. The simulation results verify the correctness of improvement.

Index Terms—Modulation strategy, boost converter, zero-voltage zero-current turn-off.
