<P>PROBLEM TO BE SOLVED: To provide an Alternating Current (AC) to AC power converter that does not require a Direct Current (DC) link or storage devices. <P>SOLUTION: An AC to AC power converter 10 has a rectifier 12 configured to receive an AC signal. An H-bridge 20 is coupled to the rectifier 12 and a DC filter 22. A DSP 16 is coupled to the rectifier 12 and to the H-bridge 20, and the DSP 16 is configured to produce a pulse to modulate a rectified input or a constant DC input to the H-bridge 20. A 60-Hz sine wave filter 26 is configured to modulate an output of the H-bridge 20 to an AC voltage having a desired frequency, and an output of the 60-Hz sine wave filter 26 is coupled to a processor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
