Abstract

The invention discloses a pulse voltage modulation circuit, comprising a high voltage input terminal, a modulation voltage output terminal, a pulse signal input terminal, and an energy storage first capacitor, a driving circuit and a modulation tube which are sequentially connected between the high voltage input terminal and the modulation voltage output terminal, wherein the driving circuit is further connected to the pulse signal input terminal and the modulation tube, and is configured to turn on the modulation tube by the pulse signal input from the pulse signal input terminal to make themodulation voltage output terminal output the voltage of the high voltage input terminal and the energy storage capacitor. The pulse voltage modulation circuit can improve the operating voltage of themodulation circuit, making the rising and falling edges of the output modulation voltage be faster, reduce the power loss of the system, and improve the efficiency of the system, thereby reducing thesystem heating and making the system lower the heat dissipation requirements.

Description

technical field [0001] The invention relates to the technical field of pulse modulation. More specifically, it relates to a pulse voltage modulation circuit. Background technique [0002] In various communication systems and radar systems today, pulse voltage modulation circuits are an indispensable part. The size of the pulse power, the rising edge and the falling edge of the pulse directly affect the main technical performance of the radar. With the development of microwave power tubes, the operating voltage and current of microwave power amplifiers are getting higher and higher. The requirements of the system for the modulation circuit are also gradually increasing. The high-voltage and high-speed requirements make it difficult for the traditional modulation circuit to meet the needs of the new system. [0003] In the existing technology, the working voltage of the modulation circuit is low, which cannot meet the needs of users. The rising and falling edges of the mod...
