Im doing a transformer based ups system, when i measure the voltage across load and battery im getting some weird graph for load which goes till 800 v and for battery is 52v

i hv made a transformer based ups where i hv a ac sourve connected to universal bridge (rectifier ) through a step down transformer to a battery to a inverter then this is step up to load . i also hv breakers so that i can show mains on amd off conditions . now when i measure the voltage across the load it is not a sine wave something tht goes till 800 v also the voltage across the battery is constant 52 but i stepped down the transformer to only 48 v i dont see and charging or discharging

Re-examine your circuit connections, component ratings, and measurement technique. Best to break down the model into simpler parts to check they are working as intended and then proceed at integrating them.
