【 摘 要 】

The new circuit design has been considered to reduce current setting time after switching in a low-dimension contour antenna applied in an electrical mineral prospecting system. Such circuit is a bridge of IGBT transistors with an inductive load. It has been shown that switching time for the circuit with a shunt and damping dissipative elements is 10 times less than that for the circuit with a resistive shunt.
