Abstract: A control system to realize input power changing along with both loads and rotate speed by an inverter bridge dragging many sets of motors, is composed of a stator voltage regulating unit (1), a motor unit (2), a rotor speed control unit (3), an inverter bridge unit (4), a control drive unit (5) and a signal processing unit (6). By setting a power factor sensor, the phase voltage and phase current of the motor stator are acquired as a control signal to regulate the input power so as to make it change with loads. At the same time, by setting a voltage sensor and a current sensor, motor rotor phase voltage, rectifier output current, overvoltage protection current and chopper working current are acquired separately as a control signal to regulate the input power so as to make it change with the rotate speed, thus realizing input power changing along with both loads and rotate speed.
