Research on Increasing Frequency-Tracking Speed for Series Resonant Inverter

This paper analyzes the influence of control circuit parameters to stability and dynamic characteristics of series resonant inverter, and proposes a simple variable frequency-bandwidth CPPLL frequency tracking circuit. The simulation results demonstrate that the theoretical analyses are correct, and the proposed control circuit can increase the frequency tracking speed of series resonant inverter greatly and has not negative inferences to the normal performance of series resonant inverter .The conclusions will benefit to design control circuit of resonant inverter and have reference values to other implementations with PLL, too.
