I have received the latest PCB versions I was taking about the last time. The Half-Bridge for the ZVS, dual Class C amplifier and the NCP5181 with Boot Strap technology. I have done testing them with two circuits and long fly wires before, now we test them on one circuit board. I did postulate that ideally the Half-Bridge should not consume more power than a class C amplifier for the same load. Can that be? We have two times the components and power consumers.
