Embodiment Construction
[0017] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0018] As shown in accompanying drawing 1, it is a schematic circuit diagram of a method for realizing a high-power pulse power supply by using the power device IGBT as a linear device. It is composed of two operational amplifiers A1 and A2 connected in series and an emitter follower connected in series with an IGBT. The collector output is connected to the current negative feedback amplifier, one end of the non-inductive resistor R1 is respectively connected to the reverse end of the emitter follower A2 and the emitter of the IGBT, and the other end of the non-inductive resistor R1 is grounded to form a linear amplifier.
[0019] Accompanying drawing 2 is the schematic diagram of the current linear amplifier power supply system (high-power pulse power supply), which consists of two controllable voltages V1 and V2, two current sources I1 an...
