A conventional UPS can supply the clean power to the load However, it may generate input current harmonics and the input power factor can be very poor Therefore, the UPS itself may be a power interruption This paper provides multifunctional converter of using single phase UPS The proposed UPS can supply the clean power to the load without polluting the mains power system The multi-functional converter provides battery charging, var compensation and harmonic suppression simultaneously It was simulated to verify this work.
