Abstract:

The Delco Electronics three-phase static frequency converter uses the Power Center approach to precision waveform generation. With this technique, 80 of the power to the load is controlled directly by a thyristor bridge circuit between a dc voltage supply and a three-phase load. The remaining 20 of the power is transferred to the load via a series of low impedance taps on an autotransformer. The taps are sequentially connected to the load such that a low harmonic content, stair-step approximation to a sine wave is provided. The purpose of this project was to determine the applicability of the Delco inverter design approach to the development of Army portable frequency converters.
