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

Buy portable and high quality car power inverters on to convert 12V DC current from to 220V pure sine wave AC current. A switch-mode converter varies its dc output current in response to load changes. The AC line voltage is rectified and then filtered to provide an unregulated high voltage DC rail to power the following DC-to-DC inverter circuit. One widely-used approach is pulse width modulation (PWM) that controls the power switch output power by varying its ON and OFF times. Up to Six High-Resolution Digital Pulsewidth Modulated (DPWM) Outputs for Supporting a Wide Range of Offline, Isolated and Non-Isolated DC/DC Topologies.

Pulse Width modulation (PWM) is a commonly used technique for generally controlling DC power to an electrical device, made practical by modern electronic power switches. Power transistors switching at 10's to 100's of kHz impose a high voltage, high A modulator circuit converts the error amplifier signal into a high frequency, pulse width modulated waveform to drive the switching power transistors. 250-ps DPWM Pulse-Width Resolution.
