Embodiment Construction

[0034] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0035] In order to solve the problems of slow response and short time of the hiccup protection of the power module of the existing radar system, this embodiment discloses a hiccup protection circuit of the power module. like figure 1 As shown, the circuit includes a reference voltage module 11 , a voltage judgment module 12 and an output protection module 13 .

[0036] Wherein, the reference voltage module 11 is used for forming the reference voltage according to the supply voltage.

[0037] The voltage judging module 12...

Abstract

The invention discloses a power supply module hiccup protection circuit, which comprises a reference voltage module which is used for forming a reference voltage according to a power supply voltage; avoltage judgment module which is used for comparing the reference voltage with an input fault voltage to obtain a feedback signal; and an output protection module which is used for outputting the output voltage of a first level and changing the first level of the output voltage into a second level when the feedback signal is used for executing the protection operation. The invention can provide the protection circuit which can respond quickly and perform hiccup protection for a long time, and the reliability of a power supply module of a radar system is improved.

Description

technical field [0001] The invention relates to the technical field of power supplies. More specifically, it relates to a power module hiccup protection circuit. Background technique [0002] With the rapid development and wide application of solid-state phased array technology, it has become a very urgent need to develop various small-volume, high-power, wide-pulse and low-ripple power modules for solid-state phased-array radar systems. [0003] The current solid-state phased array radar antenna is mainly composed of tens of thousands of transmitting components, and each transmitting component is generally divided into 2-8 channels. In terms of power supply, each transmitting component contains a high-power DC-DC (direct-current) power supply module, and then the DC-DC power supply module passes through the LDO (low drop VOUT regulator, low dropout linear regulator) respectively. Each channel is powered. The LDO not only suppresses the ripple, but also isolates the chann...
