Title: Controlling method for current of power converter
Inventor: SHIMAMURA TAKEO
IPC: H02M7/48
Filed: 1982-08-20
Abstract: PURPOSE:To completely remove the amplitude error and the phase error between the set value of a current and the actual current by containing an integrating element in an amplifier which amplifies the error amount of a DC control system. CONSTITUTION:An instruction unit 150 outputs the first first-shaft current reference value I*1alpha, the first second-shaft current reference value I*1beta of the DC amount and the first phase angle theta*0 are outputted. A detector 450 obtains with load currents i1U-i1W and phase angle theta*0 the actual first first-shaft current value I1 and the actual first second-shaft current value I1. These reference values and the actual value are led to comparators 301, 309, and the first-shaft error epsilon1alpha and the first second-shaft error epsilon1beta of the DC amounts are obtained. These errors are respectively calculated by arithmetic units 303, 310, and the second first-shaft current reference value I*1calpha and the second second-shaft current reference value I*1cbeta are obtained. Since the units 303, 310 are composed as PI amplifiers, the deviation can be completely reduced to zero to the command of the DC amount.
