Pulse-width modulation (PWM) generators are integrated in nearly every switching power device. This article shows two methods for implementing a stand-alone analog PWM waveform generator. These ...
The PLD (programmable-logic-device) code in Listing 1 creates arbitrary-resolution, pulse-width-modulated (PWM) generators. PWM generators are useful as low-bandwidth D/A converters in hardware of ...
I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...
Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...
In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...
