Abstract
A switching and control arrangement are provided along with a transformer arrangement such that semiconductor-based switches can be used in a medium DC voltage to AC inverter in a medium voltage to low voltage DC to DC converter. The switching arrangement on the secondary side of the transformer arrangement controls a current ramp up or down of switches on the primary side of the transformer that are used to convert DC to AC, thereby permitting for soft switching of those switches.
