ABSTRACT:
A radio frequency (RF) generator comprises a first half bridge including first and second power transistors; a second half bridge including first and second power transistors; an output node coupling the first and second half bridges and RF signals to a load; positive and negative rails coupled to an AC power source via rectifier; a first blocking capacitor provided between the positive rail and the load; and a second blocking capacitor provided between the negative rail and the load. The first and second blocking capacitors are configured to isolate the load from the AC power source.
