Study on DSP-based PLL-controlled superaudio induction heating power supply simulation

Main different characteristics between both series and parallel inverters are compared. The operating principle of series resonant inverter is analyzed. The Matlab 6.5 is used as simulation tool to establish the simulation model of the inverter and control system. The DSP-based PLL-controlled closed loop system is designed, and the system stability is analyzed by Jury's stability test, which may be beneficial to the researcher engaging in relevant inverters.
