摘要 |
The current from an external AC power source is rectified to charge a DC battery and conduct current therethrough in series with a load during one-half of each power cycle of the external source. During the other half of each cycle, current is conducted through the load by discharge of the battery through a transistor that is switched to its conductive state by a phase control transformer connected to the power source.
