  • Using the PWM
    operation is where the period of the PWM. output remains constant, and only the duty cycle is. In a variable period / variable duty cycle PWM both the. modified. The PWM can operate in either of two modes: duty cycle of the PWM as well as the frequency (period). • Hi-resolution mode: the PWxDCL register
  • Frequency and Resolution Options for PWM Outputs
    The PIC17C42 is equipped with two high frequency Pulse Width Modulation (PWM) outputs. In a pulse width modulated signal the period of the signal is (usually) kept fixed, while the duty cycle is varied. In this application note, we will discuss options in selecting PWM frequency and resolution

  • A Simple Circuit for Driving Microcontroller Friendly PWM Generators
    frequency of the PWM output, and the duty cycle of the clock limits the maximum PWM duty cycle of the output. Control of the duty cycle between 0 and the maximum set by the clock input is determined by the current feedback to the comparator and the output of the error amplifier. TB085 A Simple Circuit
  • Using AC PWM Drives on Non-Standard Voltages and Frequencies
    Often, there may arise the need to apply an AC PWM drive1 to input voltages such as 200, 208, 380, 415 and possibly other levels, as well as input frequencies such as 50 Hz. The AC PWM regulator utilizes a switching power supply for control power that is sourced from a DC bus. This gives the unit
