Abstract：
A novel high voltage switching circuit with parallel resonant topology is analyzed. Without adding other resonant components, this circuit makes full use of the transformer leakage inductance and winding capacitance so as to reduce the influence of the transformer parasitic parameter. Using device CD4046 to realize the switching control of MOS, this circuit can realize the constant-current charging to capacitor by operating the above resonance. The operating process of the circuit is analyzed, and the power calculation and some practical waveforms are given.
