1. Description of CCPF-1500/2000-XX
The CCPF-1500/2000-XX is a capacitor charging power supply designed for
OEM laser manufacturers. The power supply provides up to 1500J/sec for
line voltages below 140VAC and up to 2000J/sec for line voltages between
200VAC and 240AC. The main power output provides a constant current to
charge up a capacitor to the programmed value. An optional +24V is also
available for auxiliary power.
The CCPF-1500/2000-XX can be configured for maximum output voltages
up to 4000V. XX is the model designation which indicates the maximum
output voltage. As an example, a CCPF-1500 configured for 1000V
maximum output voltage is designated as a CCPF-1500-1P, where the P
indicates a positive output. Positive output is the standard polarity.

CCPF-1500/2000-XX INTERFACE
(15 Pin “D” Sub Connector Female)
PIN # TITLE/DESCRIPTION
1 INHIBIT/FAULT RESET- (Input) This pin is the basic ON/OFF control
pin for the power supply. Grounding pin 1 enables power supply
operation if all faults are clear. Applying +15V to pin 1 prevents the
inverter from operating. NOTE: In PFN applications, the power
supply should be INHIBITED via Pin 1 during the period the PFN
capacitor is discharged into the load. Noise from the discharge could
cause improper operation if the power supply is not INHIBITED.
2 N/C. Do not use.
3 OVER-TEMP STATUS INDICATOR- (Output) 10V (+/- 0.5V)
indication of over-temperature condition. This indicator is normally High
(5V) and will switch to Low (0V) to warn of a pending over-temperature
condition.
4 N/C. Do not use.
5 VOLTAGE PROGRAM- (Input) Output is programmed externally with
a 0 to +10V signal = 0 to Vout
6 OVERVOLTAGE STATUS INDICATOR- (Output) Open collector
output rated 30V, 100mA. Collector is tied internally to 4.02kohm pullup resistor. If the load becomes open circuited, the power supply will
detect the fault and shut down instantaneously, protecting itself and other
equipment from over-voltage. If this occurs, pin 6 is pulled low. To
restart, the INHIBIT/FAULT RESET function (Pin 1) must be toggled.
7 V
PEAK HOLD- (Output) Monitors output voltage with a peak hold
out
circuit. The time constant of the peak hold circuit is approximately 5
seconds. 0 to +10V = 0 to Vout

11 +15V (Output) Maximum output current is 100mA. This pin is internally

12 N/C. Do not use
13 END OF CHARGE STATUS INDICATOR- (Output) Open collector
output rated 30V, 100mA. Collector is tied internally to 4.02kohm pull-up
resistor. When the load capacitor reaches the programmed voltage, pin 13
is pulled low. Pin 13 will oscillate from high to low as the power supply
replaces charge that is bled through the feedback network.
Latched Low EOC signal is optionally available. The EOC signal will
latch Low when the load cap is fully charged and stays Low until the cap
is emptied by the PFN and the Inhibit signal will reset the EOC signal.
The Inhibit must be active for every charge/discharge cycle.

5. Typical Applications
5.1 Using a CCPF with a pulse forming network (PFN)
The above block diagram shows a typical connection between a CCPF capacitor charging
power supply and a well matched pulse forming network. In a typical operation, when
the CCPF is ENABLED via Pin 1, the INHIBIT function, the CCPF will charge up the
PFN capacitor to the programmed value and then transmit an END OF CHARGE signal
to the user. Before discharging the load capacitor into the PFN, the CCPF should be
disabled via the INHIBIT function. Once the PFN is completely discharged and the SCR
has completely extinguished, the charging function can be ENABLED via the INHIBIT
function and the CCPF will charge the capacitor again to the programmed value. PFN
designers may choose to include a limiting resistor and a reversal protection diode to
protect the power supply if there is any possibility of an arc in the PFN circuitry.

5.2 Using a CCPF with a square wave network (Reservoir Charging)
In this application, the power supply is ENABLED via the INHIBIT function and charges
up the capacitor bank to the programmed voltage. The IGBT will deliver short, high
current pulses to the flashlamp. The power supply is not INHIBITED during this process
and continuously tops the capacitor bank.

5.3 Using a CCPF with multiple PFNs or capacitors
In applications where the power supply has to charge 2 or more separate
capacitors which are discharged at different times, diodes must be used in
series with the output to prevent one cap from discharge into the other.
Also, a resistor must be in parallel with each diode to help the power supply
to “see” the cap voltage which is now blocked by the diodes.
Failure to add the parallel resistors will result in over charging the cap as the
power supply does not see the real voltage on the caps.
The diodes must have voltage rated at least 300V higher than the max
voltage and 2 times the current.
The resistor values are calculated as follows:
R (in Ohm) >= 100 * Vout.
P (in Watts) >= V^2 /R.
Multiple PFN system.
