In this circuit a transistor 2 is switched to produce an alternating voltage across the windings of a transformer 3 to provide a floating voltage source at the transformer secondary winding 4. The switching signal for the transistor is provided by an oscillator 6 and a counter 7 that divides the oscillator frequency by 16.
