1. a power transformation circuit is characterized in that, comprising:

  • Inverter circuit is configured to receive a DC signal and exports an AC signal;

    Pulse-generating circuit;

    Be configured to receive the practical AC signal that produces and produce pulse signal;

    With the change of response with a parameter of the said practical AC signal correction that produces;

    The said practical AC signal that produces is the 2nd AC signal, and a said AC signal has and the identical frequency of said the 2nd AC signal;

    AndControl circuit;

    Be coupled to said inverter circuit;

    Said control circuit is configured to receive said pulse signal and control signal is provided for said inverter circuit, makes the instantaneous voltage of a said AC signal be set at predetermined voltage in response to each said pulse signal with being repeatedThe said parameter of said the 2nd AC signal is a value of the instantaneous voltage of said the 2nd AC signal, said change be one of the said instantaneous voltage that changes to said the 2nd AC signal of a negative value from the said instantaneous voltage of said the 2nd AC signal on the occasion of.
