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 4.1. It consists of four energy-storage elements, the double
Γ
-CL:
C
-
L
and
C
-L
. The energy source is a DC voltage
V
chopped by two main switches
S
and
S
to construct a bipolar current source, . The pump inductors
L
and
L
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,
R
. The equivalent circuit diagram is shown in Figure 4.2.
