The present invention is a system and method for a direct conversion programmable power source controller. The invention uses a sampling rate optimized for a transformer used to isolate or to step up or step down the power. The power is sampled at the source frequency and that sampling is phase-angl
The present invention is a system and method for a direct conversion programmable power source controller. The invention uses a sampling rate optimized for a transformer used to isolate or to step up or step down the power. The power is sampled at the source frequency and that sampling is phase-angle modulated according to a modulating signal at a frequency representing the sum of the frequencies of the power source and the desired output. After passing the power through the transformer, the invention then again chops that power to produce a multiplication of the power sinusoid with the modulation sinusoid. The output is filtered to integrate the waveform and fed to a load in delta. Between any two terminals of the delta connection, the output voltage presents as a well-formed sinusoid of controlled amplitude and frequency.
