Construction of High Voltage Power Supply Unit for GM Counter
Khin Kyu Kyu Hlaing
Mya Sandi
High Voltage Power Supply Unit is essential for
nuclear radiation detection or counting system. A high voltage
power supply unit that is suitable to use with GM (Geiger
Muller) counter is constructed with locally available components.
The constructed high voltage unit is based on push-pull mode
and it is acceptable for low-level primary voltage (2V to 10.19V)
and delivers it at high-level secondary voltage (105V to 514V) of
transformer. To avoid the insulation problem at the transformer
secondary coil, a voltage multiplying circuit is used. The desired
voltage is rectified and multiplied by voltage multiplier unit
provides 3055V (-3 kV) DC at approximately 1mA output
current.
