IPC: H02M7/515
Filed: 1982-08-20
Abstract: PURPOSE:To completely remove an amplitude error and a phase error between the set value of a current and the actual current by containing an integrating element in an amplifier which amplifies an error amount of a DC control system. CONSTITUTION:An instruction unit 150 outputs the first amplitude reference value I*1 of DC amount and the first phase reference value theta*11. A detector 45 obtains by internal processing with load currents u1U-i1W and phase reference values theta*11 the actual amplitude value I1 and the phase error epsilon1phi. The first amplitude error beta11 and the first phase error epsilon1phi of DC amounts are respectively calculated by the first and second arithmetic units 303, 310 to become the second amplitude reference value I*1C and the second phase reference value theta*11C. Since the first and second arithmetic units 303, 310 become PI amplitude, the amplitude I*1C and the phase angle theta*11C are corrected until the first amplitude error epsilon11 and the first phase error epsilon1phi become completely zero.
