Chapter ⅣPrinciple Introduction
The circuit of the power supply has main components as following:
The main circuit includes:charging circuit,stored energy circuit,chopped-wave output and
preburning&triggering circuit.
Control Circuit includes:electrical control circuit,computer control circuit and protective
circuit.
Boost/Rectifying Circuit
Boost/Rectifying Circuit is boosted through three-phase boost system,which consist of boost
inductor and IGBT switch.The voltage is expected to rise from 380VAC to 750VDC,and will provide
the charging circuit with power.
Chopped-wave Output
The IGBT module will stop working when the electric energy of stored energy circuit is fully
charged.After that,IGBT module and storage capacitor will discharge,the charging circuit start
working.The power supply will continue this working mode.
HV Start Circuit
It’s consist of step-up Transformers,HV bridge rectifier,electric filter, current limiting
resistor,current relay,HV pulse transformer and HV triggering circuit.
Since the pulse xenon lamp has entered a state of normal glow discharge when preburning,it
will assume the negative-resistance characteristic.The preburn circuit must be assumed a high
current state to ensure of the normal operation of xenon lamp glow discharge after the end of arc
discharge.So the current limiting resistor of preburn circuit is bigger.The trigger mode of the power
supply is internal trigger.The preburing circuit will trigger automatically,when the storage capacitor is
fully charged,the HV pulse transformer can produce 15000-20000V HV to the xenon lamp,as soon as
preburning succeed,the triggering circuit will cut off by itself.
Control Circuit
There are two primary components that make up a control circuit: operating circuit and
computer controlled circuit.The operating circuit with the interlock protection function,which is by
button,contactor and electric relay to achieve the make-break-operation of pump,preburn
circuit,main power and the control power.The whole computer controlled circuit is assembled on a
circuit board.

Make sure that the cathode/anode wires are correctly connected!
Don’t connect the three-phase voltage, until all of the connector wires have been
connected correct.
The charge wires of charging Box and discharging box should be minimum 10mm2in
diameter each. In strictly accordance with the standard of our company supplies wires.
The wires from the power supply to the xenon lamps should be minimum 10mm2in
diameter each. In strictly accordance with the standard of our company supplies wires.
The wire connector of power supply input-output should be securely pressed to avoid loose
connection that may cause sparking or heating in the conductor.
Avoid binding the charge wire and discharge wire together with the lamp wire in case of
serious heating in the conductor.
Avoid binding the signal wire together with the input-output wire in case of interference.
Don’t starting the power supply, until the water chiller or water cooling system work
properly.
A high-voltage pulse output when staring the xenon lamp, so the operator should stay
away form the cable of xenon lamp electrode.
The power voltage of the product is 380V three-phase AC, high-voltage is with several parts
of the power boxes. Don't touch the charged metal parts of the connectors inside and
outside of the machine when it is on "Power On" mode or within 30 minutes after the power
is off.
It was forbidden to open the power box by the non-professionals for safety.
Check the insulation of instrument for measure is good, e.g. multimeter and oscilloscope
etc.
Ensure the gear position in the Voltage Grade in voltage measurement and the range of
the meters and instruments larger than the testing point voltage.
Ensure good ventilation and sufficient radiation space are provided when installing the
power to keep the air duct well ventilated.
