Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To form a simply structured and inexpensive detection circuit by providing a diode bridge for switching DC voltage on a primary side and two switches on a secondary side and by switching at a high frequency by an oscillator. SOLUTION: Switches 11, 12 are alternately turned on/off by an oscillator 13, and consequently voltage V72 of one of secondary coils 7b of a transformer 1 and voltage V73 of the other coil 7c are switched, so that polarity of voltage V71 of a primary coil 7a of the transformer 7 is switched. When the voltage V71 is positive, diodes 4, 5 are conductive, while when it is negative diodes 3, 6 are conductive.

The secondary coil current is led by the switches 11, 12 to a shunt resistor 15, which converts it into DC output voltage Vout for outputting.
