Power Flow
The 5KVA single-phase UPS reference design offers an integrated uninterrupted power
supply solution with Infineon microcontrollers (Figure 1). Its main control process including
PWM signals generation, output voltage feedback control, system faults and errors
managing, charger module control, modules synchronization is all handled by the control
board based on Infineon 16-bit microcontroller XC164CM. The information display with
LCD and keyboard operations are implemented by the monitoring board based on Infineon
8-bit microcontrollers XC866 (Figure 1).
