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 a power source; a first blocking capacitor provided between the positive rail and the load; a second blocking capacitor provided between the negative rail and the load; and an offline rectification circuit configured receive an alternating current (AC) from an AC power source and output a direct current (DC) to the first and second bridges, wherein the first and second blocking capacitors are configured to isolate the load from the AC power source.
