This paper proposes an optimal control method of clamp switch for ZVS bi-directional DC-DC converter. The bidirectional DC-DC
converter using the clamp switch can achieve zero voltage switching (ZVS) operation. In this topology, the clamp switch separates
the inductor current from input and output voltage and maintains minimum current for ZVS operation. The separation of the inductor
current can reduce the inductor current ripple and the power loss of the power devices. Therefore, it is important to the optimal
control method of clamp switch to improve the system efficiency. This paper proposes the optimal clamp switch control method
using micro controller unit (MCU) without the additional circuit. The proposed control is verified from PSIM simulations using 1-kW
ZVS bi-directional DC-DC converter system.
