An Overview of Buck-Boost Transformer Sizing
The buck-boost transformer size can be calculated as follows: P = I ×E 1000 = 17.5×32 1000 =0.560 kV A P = I × E 1000 = 17.5 × 32 1000 = 0.560 k V A. A buck-boost transformer larger than 0.560 kVA can be installed to boost the voltage to the required level. When both loads are turned on, the voltage at the loads is 120.3 V.
