ABSTRACT
This chapter introduces a four-element current source resonant inverter (CSRI): a cascade double Γ-type C-L circuit CSRI. Its circuit diagram is shown in Figure 15.1. It consists of four energy-storage elements, the double Γ-CL: C1-L1 and C2-L2. The energy source is a DC voltage Vin chopped by two main switches S1 and S2 to construct a bipolar current source, . The pump inductors L10 and L20 are equal to each other, and are large enough to keep the source current nearly constant during operation. The real load absorbs the delivered energy, its equivalent load should be proposed resistive, Req. The equivalent circuit diagram is shown in Figure 15.2.
