Abstract
Methods, circuit designs, systems, and devices for the conversion of high voltage alternating current (AC) to low voltage, high current direct current (DC) are described. An exemplary apparatus includes a rectifier for receiving a high voltage AC line power input and for outputting a full wave, high voltage DC, a gating component coupled to the rectifier for receiving the high voltage DC output by the rectifier, wherein the gating component is configured to gate the high voltage DC by turning on at a zero crossing level and turning off when the high voltage DC exceeds a preset voltage threshold and wherein the output of the gating component is an intermediate voltage DC capped by the preset voltage threshold, and a DC-DC converter coupled to the gating component for receiving the intermediate voltage DC output by the gating component, wherein the DC-DC converter is configured to step down and smooth out the intermediate voltage DC to a desired high current, low voltage DC output.
