Abstract
Embodiments of the invention controlling power distribution in an ablation control apparatus or the like. In one embodiment, a power switching apparatus comprises a first switch assembly having an input end to receive a power input signal, the first switch assembly having a plurality of output channels; a second switch assembly coupled to the output channels of the first switch assembly; a plurality of power receiving members coupled to the second switch assembly; and a controller controlling the first switch assembly to selectively transmit the power input signal to the output channels one at a time in a cyclical manner according to a first switching rate. The controller controls the second switch assembly to transmit the power input signal from the output channels of the first switch assembly to one subset of the power receiving members at a time according to a second switching rate, so as to transmit the power input signal to a subset of power receiving members one power receiving member at a time within the subset of power receiving members according to the first switching rate.
