A pseudo-resonant DC link for coupling direct current from a DC source to an inverter includes a plurality of switches which are controlled so as to minimize switching loss in the DC link and in the inverter. The DC link includes a capacitor and an inductor coupled through controllable switches in a manner that momentarily reduces to zero the input voltage to the inverter each time that a switch in the inverter is commutated. The controllable switches in the DC link function to allow the capacitor to resonate through the inductor and then be recharged at the end of a commutation interval. The controllable switches in the DC link are timed to that switching generally occurs under conditions of zero current.read more
