1. A drive circuit configured to drive a load, the circuit comprising:
a transformer comprising:
a transformer primary comprising one or more primary windings connected to arms that pass through a magnetic material; and
a transformer secondary comprising secondary windings connected to secondary conductors, wherein the secondary conductors pass through the inside of the arms and wherein the secondary conductors are linear where they pass through the inside of the arms;
wherein the drive circuit further comprises a voltage source configured to apply a voltage across the transformer primary.
