Abstract A variable timing control method based on voltage zero crossing detection is proposed in this paper, and is applied to the new type two coupled inductor soft-switching zero voltage transition (ZVT) inverter to realize the adaptive control of zero-voltage switching. Through real-time voltage zero crossing detection of the main switch, the delay time between auxiliary switch and main switch can be adjusted adaptively, and then the main switch turns on right after voltage drops to zero. Compared with the fixed timing control method, zero-voltage soft-switching can always be realized by the proposed method, and high-efficient operation of the inverter also can be ensured when its load changes from light to heavy. Instead of DSP software control, zero voltage detection, switches control logic, together with the gate driving circuit, can be designed and built totally by hardware, and therefore the control software is of better portability. Feasibility and effectiveness of the proposed method in this paper are verified by simulation and experimental results.
