Influence of power consumption over the input current harmonics pollution for a half-bridge power inverter

The intent of this presentation is to present the influence of power level delivered on a load over the total harmonic distorsion of input current for a power half-bridge inverter with resonant load. Half-bridge inverter is a configuration used for higher output power applications compared to single end quasi-resonant inverter. Even though it needs complicated control, half-bridge configuration has been winning popularity because it is relatively much more reliable and easier to build up higher power system.
