Problems solved by technology

Since the power consumed by the radar front load transmitting components accounts for most of the total power consumption of the radar system, this part of the load causes severe power fluctuations when working as a pulse load, making the input power on the power supply side fluctuate between no-load and full-load , leading to more serious power fluctuations on the power supply side of the radar power system, seriously affecting the stability of the power supply platform and the radar power system, power fluctuation suppression measures must be taken to improve the reliability and stability of the entire ship power supply system

Embodiment Construction

[0028] The technical solution of the present invention will be specifically described below with reference to the accompanying drawings, taking the shipborne radar as an example.

[0029] The structure of the power fluctuation suppression system is as follows figure 1 shown, including platform DC, power fluctuation suppression Boost converter, DC / DC converter, controllable switch, radar array energy storage capacitor C 1 and pulse load equivalent resistance R 1 .

[0030] The platform DC power is provided by the shipboard generator set, which is generally 500V ~ 1500V high voltage DC power. After the power fluctuation suppression Boost converter and the DC / DC converter, the radar front is provided with 8V ~ 50V low voltage DC power.

[0031] Modern radars frequently switch between multiple operating modes. The load characteristics of the radar front can be equivalent to a pulse load that operates according to a certain operating mode, such as a fixed period and a duty cycle....

Abstract

The invention discloses a power fluctuation suppression system and a design method thereof. Platform direct current is used to provide high voltage direct current, and through a power fluctuation suppression Boost converter and a DC / DC converter, low voltage direct current is output, and electrical equipment is equivalent to a controllable switch. Compared with the existing power supply system, the power fluctuation range is reduced, which can not only be applied to shipborne radar systems, but also other occasions with pulse loads. .

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a power fluctuation suppression technology. Background technique [0002] Modern radars are developing towards distributed phased array radars. The radiation power of the system is gradually increasing, and the power supply power of the system reaches the megawatt level. The capacity of the power supply equipment of some platforms is on the same power level as the power supply demand of the radar system, making the radar system and the radar system. The stability problem of the platform power supply system is becoming increasingly prominent. [0003] The multi-functional development of radar makes the working mode of pulse load more complicated, especially the large fluctuation of input power of radar system caused by millisecond pulse width, which has a serious impact on the frequency and voltage stability of the power supply platform. [0004] In order to...
