Abstract

A modular radar transmitter high-voltage power supply DC-AC converter circuit, including a control board and a power conversion board module, the control board module includes an overshoot control circuit, a protection circuit, a signal generation circuit, and a drive circuit, and the power conversion board module includes a complete Bridge conversion circuit; the overshoot control circuit controls the charging current and voltage of the high voltage power supply by detecting the ratio of the output voltage of the high voltage power supply to the start-up delay voltage; the protection circuit detects the deviation of the high voltage power supply from the preset value, and The power supply protection is carried out in the condition of the full-bridge conversion circuit; the signal generation circuit generates the drive control signal of the full-bridge conversion circuit; the drive circuit amplifies the control signal to stimulate and drive the power switch of the full-bridge conversion circuit; the full-bridge conversion circuit converts the input DC voltage through different switch states into AC voltage output. The invention has the advantages of effectively improving the output power control capability of the converter and the adaptability of the converter to the distribution parameters of the high-voltage transformer, thereby realizing universality.

Description

Technical field [0001] The invention relates to the technical field of transmitters in radar systems, in particular to a DC-AC converter of a high-voltage power supply for modular radar transmitters. Background technique [0002] With the diversification of radar platforms, aviation and aerospace platforms such as airborne and missile-borne have put forward more stringent requirements on the volume, weight, and efficiency of radar transmitters. These requirements determine that the transmitter high-voltage power supply must have a compact structure, a small volume and a high power density, while requiring high reliability. [0003] In order to achieve a small volume and high power density, one of the most effective technical approaches adopted by the high-voltage power supply is to increase the switching frequency of the converter. Since the high-voltage power supply of the radar transmitter is a high-power power supply with a very high boost ratio, with the increase of the switch...
