A power supply inverter for providing an AC output from a DC power supply. Conventional power supply inversion involves the use of bulky transformers. By using high frequency transformers which are small and light a DC power supply is converted into at least two high frequency AC outputs of different frequency. Processing and filtering the outputs followed by conversion to a bipolar waveform produces an AC power supply which is the difference of the outputs so that for example AC outputs of 50,000 Hz and 50,050 Hz produce an AC power supply of 50 Hz. Uses include back-up power supplies for computers etc. and power supplies for electric tools where mains supply is not available. |
