Abstract
A first control loop enables the inverter to be made to operate as a current generator when it recharges the batteries of a back-up power supply. Two other control loops enable the inverter to compensate on the one hand the harmonics, and on for other hand for the reactive part of the current absorbed by the load, when the inverter is on stand-by.
