    摘要： A low-frequency PWM-modulated signal and a high-frequency, unmodulated signal for generating a high-frequency PWM-modulated signal is employed directly for driving an output stage of a device for noise suppression. The low-frequency signal and the high-frequency signal is advantageously provided by a microcontroller which already has an AD converter on the input side. The microcontroller furthermore already makes a PWM output signal with a high bit width available which has the high resolution necessary for driving the loudspeaker.

    摘要： An injector driver module includes a first converter and a second converter connected between a power supply and the load. The first converter generates a first voltage output and the second converter generates a second voltage output from the power supply. Switches control the level of the supply voltage so that the voltage applied to the load can be varied depending on an operational phase of the driver. Control over the current through the load can be therefore be conducted via pulse width modulation at lower voltage levels, thereby lengthening the switching time during modulation, reducing power losses, and reducing EMI emissions.
