Beschreibung
Zusammenfassung:	An efficient d-c to d-c converter power supply has over-voltage protection, the over-voltage protection circuitry being particularly applicable for use with power supplies having high current output characteristics. A reference voltage detecting device is connected to the high voltage load line as well as the control terminal of a thyristor device which is connected in series with a resistor across the load terminals so that when an over-voltage condition exists, the thyristor device is triggered into conduction, developing a voltage across the resistor which is applied to a circuit isolating device which has its output operably connected to the oscillator and shuts off the oscillator and power supply. Supplementary over-voltage protection circuits are included to provide protection against multiple failure of various components or portions of the circuitry.
