Control of a 3-phase motor drive employing a slim DC-link

A variable speed AC motor drive, fed by a 3-phase AC supply, often consists of a 3-phase bridge diode rectifier, a DC link capacitor and a pulse width modulated inverter. Recently, a new type of capacitor known as film capacitor or slim capacitor has become popular for use in DC link. This capacitor has a lower value of capacitance and a longer...
