Delta conversion rectifier
According to one aspect, embodiments of the invention provide an AC-DC rectifier comprising an input configured to receive input AC power from an AC power source having an input AC voltage waveform, an output configured to provide output DC power to a load, an active power filter coupled to the input, an inverter coupled to the input and configured to convert the input AC voltage waveform into an output AC voltage waveform at a desired magnitude, a rectifier portion coupled between the inverter and the output and configured to convert the output AC voltage waveform into the output DC power, and a controller coupled to the active power filter and the inverter and configured to operate the active power filter to provide Power Factor Correction (PFC) at the input and to operate the inverter to provide the output AC voltage waveform at the desired magnitude to the rectifier portion.
