Load Independent Class- E−1Inverter with Shunt Capacitance

This paper proposes a load-independent class-E⁻¹ inverter with shunt capacitance. This inverter achieves the ZVS and the constant output current at any load resistances without any control, which is called load-independent mode. This paper provides waveform and design equations of the proposed inverter. We confirmed that the laboratory prototype worked with the load-independent characteristics, which denoted validities of the analytical equations.
