Title: Inverter control system
Inventor: SAWA TOSHIHIRO
IPC: H02P27/06
Filed: 1990-03-13
Abstract: PURPOSE:To prevent fluctuation of ripple current even upon modification of the connection of winding by varying the PWN carrier frequency of an inverter according to the primary impedance of motor winding at the time of connection of winding. CONSTITUTION:Since signals (b), (c) are applied, respectively, on minus and plus inputs of a comparator 29, output thereof goes High thus turning switches 25A, 27A ON and turning switches 25B, 27B OFF. Under this state, output of an integrator 21 is obtained by integrating the input signal (a) to the integrator 21. When the output increases and exceeds over the comparison voltage of the comparator 29, output thereof goes Low thus turning the switches 25A, 27A OFF and turning the switches 25B, 27B ON. Consequently, the output Vout drops below the comparison voltage -Es of the comparator 29. Since the oscillation frequency is determined by a reference voltage, an input resistance and an integration capacitor, the oscillation frequency can be modified by regulating any one of them.
