Abstract :
In this paper, an approach based on analysis for designing the class-D inverter with the nonlinear parasitic capacitance of MOSFET, is proposed. In addition, a design instance as well as its Spice simulation is also provided. The switch voltages obtained from no matter the analysis or Spice simulation, achieve the ZVS condition. Furthermore, the comparisons made between the analyzed and simulated results show that they have a good consistency and prove the validity of the analytical approach presented in this paper. Therefore, the consideration of the nonlinear parasitic capacitance is very important to achieve the ZVS specially at the high-frequency operations.
