ABSTRACT:
In high-efficiency power source applications, AC power is converted to DC power, which is isolated from the source and regulated. A level of performance is achieved that exceeds the power quality requirements of MIL-STD-704 over the extended frequency range, typically from about 360 Hz to 800 Hz. While high-efficiency and low-weight of the invention, among other benefits, are advantageous primarily in airborne systems, its use can be extended to terrestrial applications as well. The isolation, regulation and the main power processing are achieved by low-weight, high-frequency conversion stages arranged in 2 channels that produce the line harmonic content typical of the 12-pulse rectification. Control of the conversion stages provides effective rejection of line transients, while output ripple voltage is typically an order of magnitude lower than in conventional transformer rectifier units.
