<p>The voltage conversion circuit comprises a driver, a transformer, a filter and a monitor. The driver is used for processing an input signal and producing a periodic signal. The transformer has a first and a second windings and a magnetic core for transforming the periodic signal. The first winding is connected to the driver and the second winding is connected to the monitor. When a flash over is caused by a broken wire in the second winding or a bad contacting, the monitor can either detect a converted signal with a noise at a high frequency, or detect an abnormal varied voltage at the second winding, so as to produce a control signal which is given to the driver for inhibiting the input signal.</p> |
