A highly innovative new technique of developing DC to AC power sources for various applications has been described. Such technique of generating AC power is different from the conventional techniques and this new technology has been called the Solid State Power Supply (SSPS) Technology. The principle of operation depends upon high frequency switching using MOSFET bridge inverter which utilizes charge-discharge averaging principle to generate the sinusoidal AC voltage. The use of fast turn-on power MOSFETs enables the application of high frequency switching on this power technology. While the non-isolated SSPS is claimed to be transformerless, the isolated SSPS requires the use of a high frequency transformer for input-output isolation and for changing the output voltage level. The output filtering is reduced tremendously, thereby reducing the size of such power supplies. The SSPS technology is expected to revolutionize the DC to AC power conversion technology and a compactness as much as 4:1 over the current 50 KHz switching inverter is possible.
