Inverter, the weakest part of a high frequency and high power transmitter for electrical exploration, is liable to be destroyed. The reason is that the performance of the inverter is not good enough and the inverter protection is not satisfactory. Aiming at solving these problems, this paper presents a new inverter system which bases itself on a new power module-IPM and adopts right driver circuit and buffer circuit. It fits different transmitting frequencies and polar distances with proper settings of dead time, which is adjustable under the control of a micro controller.
