Total Mobile Power has developed innovative true sine-wave inverter technology giving high efficiency at low dc supply voltages and minimal no-load power. This technology will be of particular interest to manufacturers of mobile, off-grid and alternative power systems who wish to minimise power losses in the conversion to mains ac power.
A prototype 24 to 230Vac 4kW inverter using this technology has greater than 95% efficiency from 270 to 4200W and a peak efficiency of 97.2% at 1500W.
