Filed: 1978-08-24
Abstract: PURPOSE: To largely supress the direct current content of power current in a cyclo converter by removing the power frequency content to form a current standard waveform after amplifying absolutely frequency standard signal or current standard signal.  
     CONSTITUTION: A frequency command signal 10 varying in a sinusoidal manner with a constant peak value is fed through an absolute value amplifier circuit 11 and a BEF 13 for removing its power frequency component. The output of the BEF 13 is multiplied by the output of the amplifier circuit 11 by a multiplier 14, which thereupon produces a signal removing the power frequency component in the negative half cycle of the signal 10. The output signal of the multiplier 14 is also multiplied by a current command signal 15 by a multiplier 16 to thereby obtain a desired current standard 5. Sinoe the signal 15 is isolated from the BEF 13, the current standard 5 can respond as it is even if the current command signal is applied thereto with the power frequency component. Thus, it can largely suppress the direct current component of the power current in a cyclo converter to always operate stably the converter.
