Method and the potential transformer in order to convert input direct current voltage to the alternating current volts inside the systematic frequency range

摘要

In order input direct current voltage (U _E) from alternating current volts inside the systematic frequency range (U _A) to occur, the transformer (UET) the primary coil (W1) pulse width of two opposite polarity the rectangular pulse which is modulated (a and b) is given, fitting to Haami of the alternating current volts which each pulse should occur, is modulated. Impulse of both pulses is rectified in the downstream of the transformer, is based on pulse duration modulation and the pulse which consists of the impulse of the polarity which fits to Haami whom the alternating current volts which should occur continue (only d) tries to exist, by the frequency of 2 times that the alternating current volts which the pulse which is obtained should occur periodically polarity is changed, pulse width the pulse which is modulated (e) is obtained amplitude of output alternating current volts, in regard to frequency and polarity.
