Abstract :
The concept of the so-called inner feedback in three-phase current-controlled inverters with hysteretic current controllers is introduced. An inertial feedback loop is added to each controller. This modification affects the operating characteristics of the inverter by enforcing a switching pattern of low dependence on the load, resulting in significantly improved quality of the output current
