Inverters-dynamic load responses as a result of the impressed inverter output waveform

Inverters have been on the market since a need arose to produce AC power from a DC source, probably long before the beginning of PV power systems. With the growth in the PV industry, the need for better, more cost-effective inverters is ever present. At the same time, the need for a range of inverters covering a wide range of power and applications is becoming a salient issue. Currently there are various types of inverters on the market, ranging from square wave, modified sinewave, pure sinewave, lightweight high frequency inverters (sine or modified sine), heavy 50 Hz transformer topology inverters, etc. Often the cost of the inverters and not the quality of the waveform prescribe the choice of inverter. The purpose of this study is to investigate the dynamic response of various loads on various types of inverter waveforms
