  • A Simple Circuit for Driving Microcontroller Friendly PWM Generators

    The recent interest in intelligent power supplies has driven the development of a new class of microcontroller friendly PWM generators. These PWM generators are the mixed signal control blocks for Switch mode power supplies. One such device is the MCP1630. The MCP1630 contains the 3 main elements

  • Digital Current Loops and Direct PWM Control

    and plot key data for tuning and diagnostics. In addition to these “standard” advantages of digital control, the use of digital current-loop. control has several special advantages. Overwhelmingly, the power transistors in today’s motor. amplifiers are “pulse-width” modulated. Pulse-width modulation (PWM

  • Servo Amplifier Tutorial

    to the two types, linear and pulse-width-modulated (PWM) amplifiers. The PWM amplifiers are much more common, whereas linear amplifiers are used with a power rating of less than 100 watts. Further discussed is the switching method. The two common approaches, the bipolar and unipolar methods

  • Re: Microchips for LED Lighting

    Hello Urbain, Once I realized there was a schematic on your original file, I was able to view it with NeoOffice. Given the inefficient design you were provided, I would be inclined to start over with a switching-type circuit. That would be Part One of the project. The price you were qu...
