Output Voltage Ripple Suppression of High Voltage Power Supply for Ionising Radiation Detection Units

Operation and results of tests of operating model of high-voltage power supply of ionizing radiation detection units with active suppression of output voltage pulsations are described. The joint effect of the smoothing RC-filter and the circuit of active pulsation suppression on the value of their amplitude was experimentally investigated. The device was tested at an output voltage of 1 kV and a load current of 1 mA. The minimum peak-to-peak ripple amplitude achieved does not exceed 1mV.
