Resonant converters can operate at high
switching frequencies with low switching losses. However, in
order to reduce switching losses resonant frequency has an
important role in the design. In this study, a DSP based closed
loop phase locked loop (PLL) control algorithm for parallel
resonant inverter is designed and simulated with
MATLAB/Simulink. The validity of the Simulink model of
current source inverter is tested for different loads and gain
values obtained from Jury’s stability. The developed DSP
controlled parallel resonant inverter tracks the resonant
frequency and achieves soft switching.
