UPS – Microchip PIC Microcontroller based pure sinewave UPS with Schematic , Code, by Microchip Company. Online Courses to Learn Pic Microcontroller Programming. This reference design demonstrates how digital-power pc schematic automation tutorial pdf when applied to UPS applications enable easy modifications through software, the use of smaller magnetics, intelligent battery charging, higher efficiency, compact designs, reduction in audible and electrical noise via a purer sine-wave output, USB communication and low-cost overall bill-of-materials.
This reference design is Royalty Free. Charge stored in the battery is converted to AC output. The push-pull converter steps up the battery voltage to 390 VDC. DSC control the output voltage. Input and output DC voltage, primary current and heat sink temperature act as feedback signals.
A full-bridge inverter topology is used to convert the high-voltage DC to pure sine AC output. Sine-triangle PWM in unipolar configuration is used to switch inverter IGBT modules. Full-bridge with unipolar switching helps to optimize components rating, and reduces output filter size. Input DC voltage, output AC voltage, output filter current and incoming line AC voltage are used as feedback signals to implement efficient full-bridge control loop. Flyback converter is used for battery charging to prevent charging losses over other methods. In the presence of AC mains voltage, the Inverter mode is disabled, and the UPS switches to the battery charging mode. DSC device provides the reference current level with a variable duty cycle PWM signal.
Battery voltage and battery charging current are used as feedback signals to implement an intelligent charging profile, which extends the battery life.

PIC 18F452 running at 4 MHz, power saving sleep mode. 4 MHz, power saving sleep mode. Sensors are only turned on when needed. Updated on May 6, 2006. Now this was a huge project!
All sensors had to be fully tested one at a time, wireless communication had to be perfect, various LCDs were tried. A 6-pack will last a several months. The transmitter takes slightly less. The transmitter takes a nap every 30 seconds or so.
