Embodiment Construction
[0008] A microsecond-level high-power pulse current source for inductive energy storage, including an inductive charging circuit 1, an inductive discharging circuit and a clamping circuit 2. The inductive charging circuit 1 is a series connection composed of an excitation power supply V2, an inductance L and a switch tube. loop, the excitation power supply V2 injects magnetic field energy into the inductor L. The inductance discharge circuit is a series loop composed of a load, a freewheeling diode D1 and an inductance L, and the clamp circuit 2 is connected across the inductance charging circuit 1, such as figure 1 shown. The switch tube includes a field effect transistor S1, and a field effect transistor S2 composed of a plurality of field effect transistors connected in series. In the present invention, the described field effect transistor S2 is composed of 3 to 5 field effect transistors connected in series, The excitation power supply V2, the field effect transistor S1,...
