An Analysis and Modeling of the Class-E Inverter for ZVS/ZVDS at Any Duty Ratio with High Input Ripple Current

This paper presents an analysis and modeling of the class-E inverter for ZVS/ZVDS execution at any duty ratio. The methodology is to determine input current analytically under assumption that it always remains positive. latter ensured by proper selection inductance such operates either in (1) border condition mode or (2) continuous conduction regardless ripple. Using this applying boundary conditions, required capacitance determined a specified input/output voltage, output power load. shows can be achieved while selected appropriately. A comparison between analytical simulation results also formulated involving proposed other existing models. are provided different ratios demonstrate they better agreement with model state ripple current. facilitated using MAPLE®.
