High Voltage Cassette Power Supplies
High Voltage Cassette Power Supplies, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.
