Problems solved by technology

This feature of the circuit requires that there should be no inert components such as inductors and capacitors used to suppress output ripple in the main circuit of the circuit, because the electric energy stored on such components makes the circuit unable to quickly cut off the output voltage within 1ms
This brings great difficulty to power supply ripple suppression.

Abstract

In the invention, for effectively suppressing the output ripple, a non carbon brush electromagnetic voltage regulator controlled by a DC motor is used as a controller; a triangle winding and a star winding are used at the secondary of the high voltage transformer to replace the 6 pulses full wave rectification technology normally using one winding and to compose 2 pulses rectification technology. By the invention, after rectification, the P-P value of the ripple factor is reduced from 13.4% to 3.4%; and after adding an electronic voltage stabilizing unit composed of transistors, the ripple factor can be reduced from 3.4% to 0.1%.

Description

technical field [0001] The invention relates to a DC constant-voltage constant-current power supply dedicated to a high-voltage klystron device, belonging to the technical field of DC constant-voltage constant-current power supply. Background technique [0002] Under normal conditions, the high-voltage klystron device is required to output 23KV high voltage and 4A output current to the load of the power supply. The klystron not only requires the power supply to have fast shutdown performance, but also requires extremely small ripple voltage, and the ripple coefficient index is 0.1%. Because the value of a klystron is hundreds of thousands of yuan, once the load current exceeds 4A, it means that the klystron may be damaged. Therefore, the power supply must cut off the output high voltage and current within 1ms. This feature of the circuit requires that there should be no inert components such as inductors and capacitors used to suppress output ripple in the main circuit of ...
