Title: Power converter
Inventor: TANIZAKI TOSHIMASA
IPC: H02P9/00
Filed: 1994-12-27
Abstract: PURPOSE: To enable a power converter to have a lagged-phase current which offsets a leading current generated from a capacitor by adding a sinusoidal waveform which is lagged in phase by a specific angle and the output of a multiplier to a reference sinusoidal waveform and using the sum as the input current commanding value of a capacitor output section. CONSTITUTION: The second output waveform of a reference sinusoidal waveform generating section 76 given to a multiplier 77c is lagged in phase from a reference sinusoidal waveform by 90 deg.C. The phase of the second output waveform is lagged from that of the current 1c of a capacitor 5 by 180 deg.C. The sum of a waveform ILAG* obtained by multiplying the second output waveform by an appropriate coefficient and another waveform Id* is found by means of an adder 77b and the sum is used as the new input current command 1* of a capacitor output section 4. The input current IL4 of the section 4 following the command 1* has the same waveform as the command 1* has and this current IL4 is composed of the leading current flowing to the capacitor 5 and the opposite-phase current ILAG.  A lagged-phase current which offsets the leading current can be generated by making the gain Ic of the multiplier 77c a little larger.
