| Summary: | Using laser sweep frequency to start during series type IGBT half-bridge inverter working, the frequency reduces from 4000Hz gradually, and when the load frequency is lower than the natural resonant frequency, the inverter will be short-circuited in the state of capacitive working, which will destroy the equipment. In order to avoid this event, a phase-locked loop control circuit was designed to ensure the inverter work in the emotional state,when the operating frequency was close to resonance frequency, the frequency would be locked in quasi-resonant state. Matlab / Simulink software is used to build simulation models to verify correctness of the design. Finally, the feasibility of the design is verified through prototype experiment, and the test results are analyzed. |
