Pulse-width Modulated DC-DC Power Converters Marian K. Kazimierczuk
Publisher: Wiley

The modules, which include an The low-voltage converters are made with a proven, patented design using discrete pulse width modulation circuitry and known radiation performance components de-rated per MIL-STD-975. Up to Six High-Resolution Digital Pulsewidth Modulated (DPWM) Outputs for Supporting a Wide Range of Offline, Isolated and Non-Isolated DC/DC Topologies. In practice the motor injects a lot of electrical noise to the power supply and this can crash the microprocessor, so it's best to use an external plug-pack that plugs into the external socket (top right of Figure 4). In theory be used to drive a small motor. This simple pulse width modulation DC motor control eliminates these problems. By the PWM pulse width modulation control IGBT control turned on or off. While the latter approach works well, it generates heat and hence wastes power. The USB stack is written in C that runs . Notable hardware interfaces include digital IO with switches and LEDs, analogue inputs, three channels of PWM (Pulse Width Modulation), a serial port, and seven open collector drivers for motors.
