Description of CCPF-500/750 Power Supply
The CCPF-500/750-XX capacitor charging power supplies are designed for OEM laser
manufacturers. The CCPF-500 power supply provides up to 500 J/s average charging
power for capacitor discharge PFN applications with universal AC mains input from 100
to 240 VAC. The CCPF-750 power supply provides up to 750 J/s charging power
operating from 200 to 240 VAC mains. The power output provides a constant current to
charge up a capacitor to the programmed value.
The CCPF-500/750-XX can be configured for maximum output voltages up to 4000V
where the XX indicates the maximum output voltage. As an example, a CCPF-500
configured for 1000V maximum output voltage is designated as a CCPF-500-1P, where P
indicates a positive output, which is the standard polarity.
The CCPF takes AC mains power input and rectifies it by the input rectifier bridge. The
rectified voltage is boosted to non-isolated 400 VDC by the Power Factor Correction
(PFC) circuit. The purpose of the PFC is to force the input current to be in phase with the
input voltage, close to unity power factor, such that from 20% to 100% load the power
factor is better than 98%. The PFC also produces the auxiliary power for the fans and
control circuits. The 400 VDC power is the source for the inverter to generate the high
output voltage for the capacitor load.
