4 CONVERTER CUM INVERTER WITH
SERIES LC RESONANT TOPOLOGY AND
SIMULATION RESULTS
The design parameters are already discussed in the previous
section and the circuit which shown in Figure 4 is simulated
using the ORCAD simulation tool. We assume ideal switches
and that the load capacitor connected here is the reflected load
capacitor referred to the primary side of the high frequency
transformer. The voltage profile across the converter cum
inverter circuit is shown in Figure 4.
The voltage profile across the load capacitor is shown in
Figure 5. The voltage obtained across inverter terminals are
one and same is already shown in Figure 2. Current through
the resonant inductor is shown in Figure 6. ZCS is possible in
this topology operating when fr ≥ 2fs
