摘要： The present disclosure relates to a resonance circuit for DC-link voltage control in a DC-to-AC inverter. The resonance circuit comprises two active switches. Before the active switches of the DC-to-AC inverter are turned on, a DC-link voltage is isolated by the active switches and the active switches of the DC-to-AC inverter are discharged by the resonance circuit to zero voltage at both ends. Then, the active switches of the DC-to-AC inverter are turned on again after the DC-link voltage is charged by the resonance circuit until the DC-link voltage restores to a normal voltage value. Hence, the active switches of the DC-to-AC inverter achieve zero-voltage switching. Not only the switching loss can be reduced to enhance the conversion efficiency, but also the electro-magnetic interference as well as the RF interference due to dynamic transient changes of the voltage (dv/dt) and of the current (di/dt) can be lowered.
