High and low voltage power supplies.
Bipolar clocked circuit HCB series from 1.25kV to 20kV / 1.4W to 200W Bipolar high-voltage power supplies consist of 2 primary switched-mode power supplies with pulse width modulation. The rectified mains voltage is chopped into square-wave pulses of constant frequency, transformed, rectified and smoothed. The square wave voltage is width modulated for regulation. The two switched-mode power supplies are connected to one another at the output and are operated in opposite directions. The output can thus be continuously controlled by "0".

More infoThe mains voltage is transformed according to the required maximum output voltage. A controlled rectifier with thyristors (phase control) is located on the secondary side of the transformer. The rectified voltage is used to charge the capacitor bank of the intermediate circuit, from where the voltage is sent to the output via a serial control transistor. The thyristors are switched on with a certain delay after the zero crossing of the mains voltage. This regulates the energy flow in such a way that the voltage drop across the regulating transistor assumes a defined value (pre-stabilization). The final stability of the output values ??is determined by the control transistor (main control).

In the de-excitation mode, the actuator is controlled as a current sink. The resulting power loss is dissipated via air or water cooling.
