A new concept of identifying the most preferable load to be connected in a single phase full bridge inverter undergoing delta modulation has been provided in this paper. The best load is selected depending on the minimized Total Harmonic Distortion (THD) that depicts the presence of little amount of harmonics at the output response of the inverter as it is undisputedly the case that harmonics cause some perilous effects including unbalance and excessive neutral currents, interference in nearby communication networks and disturbance to other consumers, torque pulsations in electric motors and so forth. This paper reveals that a full bridge inverter operates more precisely with RC load having only 0.4084% THD as compared to RLC load and RL load. As a consequence, based on this, RC load has been considered as the most likely used load.
