Abstract
A topology for a medium voltage to low voltage 3-phase power converter is proposed. It consists of a clean power rectifier followed by multiple isolated DC to DC converters using commercially available high frequency transformers with very low core losses when driven by a quasi-resonant inverter operating in the 20 to 50 kHz range. The DC to DC input DC busses are placed in series, while the outputs are in parallel to effect the reduction in voltage from medium to low. Finally a DC to AC inverter re-constructs a 3-phase voltage, which after filtering, provides high quality power for low voltage loads. This proposal defines development efforts to identify the appropriate rectifier topology if clean input currents are required, to build and test a breadboard high frequency transformer, and to refine the design of the output DC to AC inverter and filters.
