This work explains the design and test of a passive filter circuit precisely measuring the dc component in the inverter output current. The filtered dc signal is then used to control the single phase inverter for the objective to keep the dc injection low — below the standard limit. Single phase inverters are ideal for use in home appliances, power tools, office equipment, water pumping in agriculture, adjustable speed ac drives, induction heating, vehicles UPS, and grid connected applications. harmonics can be eliminated using a filter. nevertheless PWM operated are very popular in all industrial equipments. The dc current injection may cause magnetic saturation of the power transformers. To solve this issue, this paper thus proposes an effective current control strategy and ompensation method, which does not require any.
