METHOD FOR CONVERSION OF AC VOLTAGE TO AC VOLTAGE OF HIGH FREQUENCY

摘要

A method for conversion of network frequency voltage to voltage of high frequency multiple to network frequency comprises supply of voltage of network frequency to an oscillatory load link using both half-periods of network frequency, in the interval of network voltage pause the current half-wave passes through a circuit. Network voltage is supplied to the oscillatory link, shaped using the total control signal comprising a sum of sinusoidal signal of oscillatory link resonant frequency and linearly varying signal of double resonant frequency of oscillatory link and negative value of signal proportional to current of oscillatory load link. Voltage of the oscillatory link is removed in the moment of negative value of total control signal; network voltage is again supplied in the moment of positive value of the total control signal.
