Claim 5:
6. A control circuit according to claim 5, wherein the first FET acts as a first diode when off and the second FET acts as a second diode when off and wherein a phasing of the first and second inductor coils with respect to each other is arranged such that when the first inductor coil is being driven to heat the susceptor arrangement, a voltage induced in the second inductor coil by the first inductor coil puts the second diode in reverse bias to prevent current sufficient to cause significant heating of the susceptor arrangement from flowing in the second inductor coil, and when the second inductor coil is being driven to heat the susceptor arrangement, a voltage induced in the first inductor coil by the second inductor coil puts the first diode in reverse bias to prevent current sufficient to cause significant heating of the susceptor arrangement from flowing in the first inductor coil.
