    摘要： The present invention supplies a position detection circuit, and a motor controller, that can not only obtain rotor position detection signals properly over the entire PWM control region, but also obtain these signals properly during PAM control. In a brushless motor controller based on the present invention to detect the magnetic pole position of the stator in the motor in accordance with the stator coil terminal voltages of multiple phases and control the energization of the stator coils, the comparison result information signal, after being obtained through comparison between the detected voltage values corresponding to the foregoing terminal voltages, and a reference voltage value, is directly entered into control circuits, then the position of the rotor in the motor is properly detected immediately after power-on switching, without a rotor position detection inhibition time interval being provided, and the motor is controlled properly.

    摘要： In a motor driving unit controlled by switching to/from PWM control from/to PAM control so that the maximum limit of motor speed can be increased and, at the same time, the unit can be operated at maximum efficiency during steady-state operation, the motor speed is controlled by maintaining the DC voltage command to the converter control circuit constant, but altering the conduction ratio command value to the inverter control circuit when the load to the motor is low, and by maintaining the conduction ratio command to the inverter control circuit constant, but altering the DC voltage command to the converter control circuit. There is a commutating phase control circuit that alters the commutating timing of the coil of the motor, and the motor is so controlled that the efficiency reaches the maximum limit during steady-state operation and the speed reaches the maximum limit during high-speed operation.

The DC voltage control circuit, when the output of the speed control circuit reaches a predetermined value, outputs a signal to cause the DC voltage to increase or decrease to the converter control circuit. The output of the speed control circuit is a duty ratio signal or a speed deviation signal representing a deviation of the calculated speed value from the speed command value.

    摘要： A switching circuit can reduce switching power loss and can vary at least one of the switching frequency and the conduction rate of switching of the switching circuit with less dependency on a frequency of a resonating circuit. A converter unit employs the switching circuit for expansion of control range of an output voltage. A primary switching element forming the switching circuit is provided with a resonance circuit and an auxiliary switching element. With the auxiliary switching element, resonance operation is achieved. The switching circuit is applicable to switching portions of a DC-DC converter unit, an inverter or the like.
