Abstract


Based on the analysis magnetron sputtering process on the basis of the background to determine the doubler rectifier ZVS PWM DC-DC converter power supply as its target electrode core , the transformer secondary side of the converter filter inductor energy over a wide load range to achieve zero-voltage switching device master switch. Because leakage inductance is small, no duty is lost , while the output rectifier diode at zero voltage conditions to achieve commutation , there is no reverse recovery problems , there is no voltage spikes. In addition, a detailed analysis of the working principle of the converter is given a specific parameter selection method . Target pole power control part adopts the peak current control mode with phase-shifted soft-switching technology combined with the program , elaborated peak current control features which gives the actual slope compensation circuit and its design method . Paper output power through different primary circuit simulation results verify the feasibility of the program . In addition, the introduction of the current-doubler rectifier ZVS PWM three-level DC converter ( half bridge ) , the main switch on the inverter bridge voltage is reduced to half and improve the working conditions of the output filter . Papers detailed analysis of the converter working principle, given the specific parameter selection method , simulation results demonstrate the feasibility of the scheme .
