  • 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
  • Using PWM to Generate Analog Output
    low-pass filters. This application note describes the design criteria of the analog filters necessary and the requirements of the PWM frequency. Later in this application note, a simple RC low-pass filter is designed to convert PWM speech signals of 4 kHz bandwidth.
  • PWM, A Software Solution using the 16CXXX Devices
    accurate and flexible PWM output, which is characterized by the following: 1. PWM frequency up to 19.6 kHz (20 MHz crystal). 2. Variable duty cycle from 0% to 100%. 3. 8-bit resolution. 4. PWM step size of 1 TCY (Instruction Cycle Time). 5. Simultaneous generation of a system time clock.
  • 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
  • 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.
  • D/A Conversion Using PWM and R-2R Ladders to Generate Sine and DTMF Waveforms
    of complex analog waveforms.: (PWM and R-2R Ladder). Both the Pulse Width Modulation (PWM) and resistor ladders require only a few external components to create a D/A converter with the PICmicro? microcontroller series. These techniques can be used to generate dual-tone multiplexed frequencies (DTMF
  • Monitoring Variable Frequency Drives (VFD)
    (PWM)] controls the effective voltage. To help "shape" the synthesized sine wave, intermixed positive and negative pulses are used at lower displacement of the synthesized sine wave.
  • Reducing Adjustable Frequency Drive (AFD)-caused Harmonics at Partial Loads
    for pulse width modulated (PWM) AC adjustable frequency drives (AFDs).
