摘要： PROBLEM TO BE SOLVED: To provide a speed controller which can stably control the speed of a motor by controlling the speed with the output of an inverter means, which converts a DC output voltage from a converter means into an AC voltage the pulse width of which is modulated at a prescribed duty ratio. SOLUTION: Although an inverter circuit 17 supplies an inputted DC voltage to a motor 31 after converting the voltage into an AC voltage of a desired magnitude, the magnitude of the AC voltage supplied in the end to the motor 31 is controlled by changing a DC voltage Vdc of a converter circuit 13 and the duty ratio of an inverter circuit 17. The speed of the motor 31 is controlled with a PWM control mode, in a region where the frequency of the motor 31 is low, with a PAM control mode in a region where the frequency of the motor 31 is high, and with a combined PWM/PAM control mode in a region where the motor 31 becomes unstable, when the control mode is switched between the PWM and PAM. Therefore, the motor 31 can be operated stably in the full speed region of the motor 31, because the voltage ripples which occur when the motor 31 is unstable due to the switching of the control mode between PWM and PAM are suppressed.

摘要： PROBLEM TO BE SOLVED: To maintain a power factor at a specific value or higher, regardless of the load conditions by varying the switching frequency of the current- switching means of a power factor improvement circuit. SOLUTION: A potential difference across a current detection resistor 7 is transmitted to an amplifier 11 and a comparator 20 via an amplifier 8. The comparator 20 compares the output signal of a current detection part with a reference level and turns on a switching element 21, when the output level exceeds the reference level. Therefore, a composite resistor, where resistor 18 and 19 are in parallel, is formed to reduce the apparent resistance, thus reducing the operating frequency of a signal generator and the switching frequency of a current switching means 1, in synchronization with it. On the other hand, when the output signal of an amplifier 8 is lower than the reference level, a switching element 21 is off, and the operating frequency of the signal generator does not change, thus maintaining a power factor at a high level of 0.9 or more.
