Abstract

The invention discloses a high-power pulse load power device with rapid dynamic response and a control method thereof. Alternating current of a power supply source is rectified through a power matching network and converted into direct current, then, power is supplied to a pulse load, pulse load characteristics are eliminated through an energy storage capacitor, a super-capacitor, a two-way Buck/Boost converter and a control circuit thereof, the two-way converter and the super-capacitor are combined, and the problem of the power adaptability of the pulse load and the power source is solved. The device can be used for electronic countermeasures equipment with any changes of the load pulse frequency and power, and is applicable to any power supply system. The device has the advantages that the utilization rate of the power supply source is high, the adaptability is high, control is easy and reliable, and the transient response speed is high.

Description

technical field [0001] The invention relates to the technical field of pulse load power supplies, in particular to a high-power pulse load power supply device with fast dynamic response and a control method thereof. Background technique [0002] The output signal of electronic countermeasure equipment generally has a wide frequency band and pulse-changing characteristics, which put forward higher requirements for the stability of its generator power supply. When the proportion of the pulse change power capacity of the electronic countermeasure equipment to the generator output power capacity exceeds 40%, and the pulse change frequency is consistent with the closed-loop adjustment frequency of the generator, the output voltage amplitude of the generator will be unstable, and the modulation coefficient will exceed GJB181 The standard stipulates the requirements, which in turn affects the stability and normal operation of electronic countermeasure equipment. [0003] The exist...
