Abstract

Abstract: Electromagnetic detection device is a research focus. In this paper, frequency domain electromagnetic detection transmitter topology structure, designed with up and down along the clamp, and the output current phase connection the launch of constant current source circuit, design of the clamping voltage source capacitance inductance value, constant current, system model is established. The simulation results show that the frequency domain electromagnetic detection emission function under the condition of inductive load is bigger, high firing frequency, output current amplitude, 3 times greater than that of the conventional bridge type transmission circuit. Besides, ac square wave is stable, with good linearity, etc.

Key words: electromagnetic detection machine, high firing frequency, strong stability, study design
