Abstract A method of the high voltage and high frequency parallel resonant converter with capacitive output filter which has the minimal peak input current is introduced. When the equivalent output voltage is equal to the input voltage, the waveform of the input current is similar to rectangular, and therefore the circuit has the minimum value of input peak current. Based on the analysis of the operational principle of the capacitive output filter parallel resonant circuit, mathematic description is obtained for each of the different operational stage. The analytic expressions and curves reflecting the characteristics of the system are obtained by further deducing, which can be used in the design of the circuit parameters and analysis of system characteristics. A 24kV/10kW output prototype was built to verify the theoretic analysis. Experimental results show that the circuit has the minimal peak input current with existing parameters and can achieve constant voltage regulation by the use of duty ratio control in full load range.
