A secondary winding 158 of the power transformer 156 is contained in the isolated stage 152 and may comprise a tapped configuration (e.g., a center-tapped or non-center tapped configuration) to define drive signal outputs 160a, 160b, 160c for outputting drive signals to different surgical devices, such as, for example, an ultrasonic surgical device 104 and an electrosurgical device 106.
In particular, *drive signal outputs 160a, 160c may output a drive signal* (e.g., a 420V RMS drive signal) to an ultrasonic surgical device 104, and drive signal outputs 160b, 160c may output a drive signal (e.g., a 100V RMS drive signal) to an electrosurgical device 106, with output 160b corresponding to the center tap of the power transformer 156.
The non-isolated stage 154 may comprise a power amplifier 162 having an output connected to a primary winding 164 of the power transformer 156.
In certain embodiments the power amplifier 162 may comprise a push-pull amplifier, for example.
