摘要： PROBLEM TO BE SOLVED: To reduce noise generated from a piezo actuator drive device.SOLUTION: In a piezo actuator drive device 1, during execution of charge/discharge control by a charge/discharge control unit 17, when a current detection unit 16 is detecting a piezo current, a noise propagation prevention switch control unit 19 turns on a noise propagation prevention switch 18 and when the current detection unit 16 is not detecting a piezo current, the noise propagation prevention switch control unit 19 turns off the noise propagation prevention switch 18.

摘要： PROBLEM TO BE SOLVED: To control the rate of change in discharge energy of piezo actuator (hereinafter referred to as piezo) at a desired fixed value. SOLUTION: In a driving unit of the piezo 1, the piezo 1 is discharged by repeating such an operation that a discharge switch 10 is turned on until a discharge current of the piezo 1 becomes a peak-side threshold Ip if a drive signal becomes low, and the switch 10 is turned on again if the discharge current decreases to a bottom-side threshold Ib when the switch 10 is turned off. In this case, a threshold setting circuit 20 is provided which raises the peak-side threshold Ip in proportion to a time duration. The threshold setting circuit 20 receives values such as a charging energy E0 charged in the piezo 1, a discharge energy ΔE to be discharged from the piezo 1 and a discharging time T and a bottom-side threshold Ib. Based on each of the values and the charge potential amount Q0 detected at the time of charging the piezo 1, a slope and an intercept of Ip for setting the change rate of discharge energy as "ΔE/T" are determined, and the Ip is set based on the slope, the intercept and the elapsed time t from the start of discharge.

摘要： PROBLEM TO BE SOLVED: To prevent an output voltage from decreasing due to a voltage drop caused by the equivalent series resistance component of a buffer capacitor in a circuit for supplying a current intermittently from the buffer capacitor. SOLUTION: A high capacity buffer capacitor 13 is connected in parallel with a correction capacitor 14 having resistance lower than the equivalent series resistance component thereof thus suppressing the voltage drop. An output voltage drop during power supply resulting from the fact that the capacity of the buffer capacitor 13 is lower than that of the correction capacitor 14 is supplemented by moving charges from the buffer capacitor 13 to the correction capacitor 14 when power is not supplied to a load 6.

摘要： PROBLEM TO BE SOLVED: To accurately detect the rotational state of a DC motor, without preparing a sensor, such as an encoder.SOLUTION: A motor 2 has a configuration in which a capacitor C1 is connected, in parallel with a first phase coil L1 out of the first phase coil L1, a second phase coil L2 and a third phase coil L3. The configuration alters the impedance of the motor circuit in two steps at each 180 degree rotation of a rotor. A control section 6 drives the motor 2 by using the PWM control. In other words, a current flowing the motor 2 pulsates according to ON-OFF switching of a drive switch MOS by the PWM control. The PWM control results in that the motor current has AC components. Additionally, the amplitudes of the AC components change according to the change of the impedance of the motor circuit following the rotation of the rotor. Here, the control section 6 detects the rotational angle and the rotational speed of the motor 2, based on the amplitude change of the AC components.
