摘要 |
<p>An output transformer for an inverter driven by a pulsating voltage obtained through the full wave rectification of a low frequency alternating current voltage is provided with an auxiliary winding, and a high frequency voltage obtained from the auxiliary winding is rectified to obtain a voltage for charging a capacitor. The voltage across the capacitor is used as an auxiliary voltage together with the pulsating voltage for driving the inverter. The circuit for charging the capacitor includes a current limiting inductor having first and second coil sections, through which the charging current flows alternately in opposite directions depending upon the polarity of the high frequency voltage.</p> |
