    摘要: A motor drive apparatus and motor drive method reduce vibration and acoustic noise by not requiring a non-activation period for rotor position detection, and enable stable, high efficiency motor drive. A control voltage generator generates a control voltage based on the frequency of the speed signal FG output from a speed detection unit, and the amplitude of the control voltage is controlled based on a torque control signal EC. The phase difference generator detects the phase difference between the control voltage and the zero cross signal of the motor current detected from the motor terminal voltages. A control voltage generator controls the phase of the control voltage so that the phase difference goes to zero, thus accomplishing sensor-less motor drive.

    摘要: Problems with accuracy reading position detection signal peaks and minute phase differences in the detection current make motor drive control easily susceptible to differences in motor characteristics. The rotor position is determined based on whether or not a neutral point difference voltage, which is the difference voltage between the neutral point voltage and the pseudo-neutral-point voltage when the motor phases are selectively energized, exceeds a specific threshold value. The phase energized to start the motor is determined based on this determination and the motor is energized accordingly to start. Instead of switching directly from the search step at the initial rotor position to the back-EMF voltage mode, a search and start mode that creates initial rotor speed sufficient to start the motor is executed before entering the back-EMF voltage mode.

    摘要: An audio signal processing apparatus for outputting an input digital audio signal as a positive phase PWM signal and a negative phase PWM signal. The resolution of the input digital audio signal is converted to a low resolution and noise shaping is performed to generate a positive phase digital signal (REF_P) and a negative phase digital signal (REF_N). Both signal patterns are compared at a buffer and pattern comparator section when muting. If the signal patterns match, a selector outputs a set value having 50% duty instead of the digital signals to optimize timing for switching to 50% duty when muting.

    摘要: A motor driving part has half bridge circuits in which a high potential side drive transistor and a low potential side drive transistor are connected in series to each other, and a connection point therebetween serves as a stator winding driving terminal of each phase of a motor. A rotor position detector detects a rotor position of the motor and outputs a rotor position signal. The current phase detector detects the phase of a phase current flowing in the stator winding driving terminal. A voltage signal generator controls and generates a voltage profile signal such that a first phase difference that is a difference between the phase of the phase current and the phase of the rotor position signal is kept to a predetermined electrical angle. A driving signal generator generates a PWM signal that drives the drive transistor of each phase depending on the voltage profile signal.

    摘要: Optical disc drives designed for reduced power consumption switch the supply voltage in three stages between first, second, and third power supplies, but the reduction in power consumption that is possible in the drive circuits with three stage switching control is limited. A drive output tracking signal is generated according to the waveform of the drive output that drives the focus and tracking actuators, and this drive output tracking signal is applied to a step-up type focusing and tracking power supply. The step-up power supply controls the fixed output according to the drive output tracking signal, and when the drive output is greater than the fixed output, control output that is greater than or equal to the fixed output and slightly greater than the drive output is generated. This control output is supplied to the focus and tracking drive circuits to produce drive output.
