Clocked circuit for high performance (with air or oil insulation) HCH series from 650V to 300kV / 20kW to 50kW 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.

SPECIAL FEATURES: - Switching control - Low ripple - High stability - High control speed - Low stored energy - Output assembly air or oil insulated depending on the voltage class Technical file
