Abstract Aiming at the problem of constant current charging of the on-off storage capacitors of the permanent magnet mechanism of the vacuum circuit breaker, based on the analysis of the output characteristics of the resonant current discontinuous mode (DCM) of the LCC resonant converter, a fuzzy constant current control algorithm was used. In order to solve the LCC resonant converter with charging voltage rise, traditional PFM control unable to maintain a constant current output and lead to power transmission loss of the defect, in this paper, by applying the idea of critical intermittent frequency tracking control, eliminating the accurate measurement of the parasitic capacitance parameter,the mathematical model of the critical frequency of intermittent tracking method was presented, and the fuzzy controller was established combining the real-time critical intermittent and reverse the resonant frequency to realize current zero cut-off and synchronous stream, and improve the efficiency of the power transmission, realize the energy storage capacity of permanent magnetic actuator for fast charging with constant current. The experimental results show that the fuzzy constant current control algorithm and the critical interrupted frequency tracking method proposed in this paper realize the constant current charging of the storage capacitor and have engineering feasibility.
