ABSTRACT:
A three phase one kilo-hertz power supply which generates a three phase pr single having a line to line voltage of 22 VRMS. The power supply is adapted to operate with an input power source of 90 to 264 VRMS having a frequency range of 50 hertz to 1000 hertz. The power supply comprises three electrically programmable read only memories with each memory containing 1024 point, eight bit binary data representations for generating one complete cycle of a sine wave. Addressing is provided by a binary counter which also generates a 1.024 MHz sampling signal for use by three digital-to-analog converters. Each digital-to-analog converter converts the 1024 point, eight bit binary data representations to a sine wave having a frequency of one kilo-hertz resulting in three sine waves which are phase separated by 120 degrees. Each sine wave is amplified and filtered by an anti-aliasing filter which attenuates selected undesirable frequencies from the sine wave eliminating any distortion effects in the sine wave signal caused by digital to analog sampling.
