Transformer coupling of low level voltages to control powerdevices has three main advantages: DC isolation, secondaryvoltages step up or step down ability, and variable outputimpedance. The conventional transformer switching methodsare limited to AC signals; since the flux, in an ungappedcore,needs resetting every half cycle of the pulse period to preventcore saturation. Also, the primary of the transformer must maintainvolt-second balance; meaning that the primary voltagetimes the seconds applied must equal negative primary voltagetimes the seconds applied. If the time of the reset pulse is shortwith respect to the on time pulse, for the same input voltage, alarger primary voltage will couple into the secondary.
