A system and method of generating RF includes an RF generator, a variable DC power supply, and a comparator. The RF generator has an RF output coupled to an input of the transducer. The variable DC power supply has a control input and a DC output coupled to the RF generator. The comparator includes a first input coupled to a set point control signal, a second input coupled to the RF generator RF output, and a control signal output coupled to a voltage control input on the variable DC power supply.
