Offline UPS Reference Design Using the dsPIC DSC
|
From Microchip Technology, Inc.
The reference design in this application note describes the design of an Offline Uninterruptible Power Supply (UPS) using a Switch Mode Power Supply (SMPS) dsPIC® Digital Signal Controller (DSC). The Offline UPS Reference Design consists of three major UPS topology blocks: 1)Push-Pull Converter (steps up the DC battery voltage to a constant high-voltage DC) 2)Full-Bridge Inverter (converts DC voltage to a sinusoidal AC output) 3)Flyback Switch Mode Charger (current source and charges battery with constant current) Products & Services
Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator.
