N2 - A soft switching control strategy for the Four-Switch Buck-Boost (FSBB) converter is proposed to achieve zero-voltage switching (ZVS) for all switches. The conventional duty-cycle-controlled cannot achieve ZVS for wide load range at the same time. Meanwhile, the conventional control strategy cannot work in a wide conversion ratio with the dead zone issue. In this paper, the soft switching control strategy for the FSBB converter is achieved by phase shift control. The converter works in two working major modes. It can cover the whole load and work in a wide conversion ratio. ZVS can be achieved in each mode. Finally, the experimental prototype verifies the control strategy.
