Equivalent alternative power supply circuit for thermal battery and power supply method for equivalent alternative thermal battery

Abstract

The invention relates to an equivalent alternative power supply circuit for a thermal battery and a power supply method for an equivalent alternative thermal battery, which belongs to the technical field of alternative power supplies in the experimental stage, and solves the problem that the existing thermal battery alternative power supply cannot output current and circuits that meet the needs of the controlled circuit The structure is complex and requires the cooperation of software and hardware. The power supply circuit includes a first delay circuit and a second delay circuit; according to the current size required in the working process of the controlled circuit, the DC power supply is selected to be delayed by the first delay circuit or the second delay circuit. control circuit power supply; the first delay circuit includes the first magnetic latching relay and the first delay relay, the sum of the delay time of the two is equal to the delay time of the thermal battery; the second delay circuit includes the second magnetic latching relay, the second delay time Two delay relays and high-power electromagnetic relays, the sum of the delay times of the three is equal to the delay time of the thermal battery. The output circuit has a simple structure, can be realized only by hardware circuit, has low cost and strong stability.

Description

technical field [0001] The invention relates to the technical field of alternative power supplies in the experimental stage, in particular to an equivalent alternative power supply circuit for thermal batteries and a power supply method for equivalent alternative thermal batteries. Background technique [0002] The thermal battery uses molten salt as the electrolyte, and is a disposable reserve battery activated by igniting the heat source by an automatic activation mechanism to melt the electrolyte. It has the characteristics of high power discharge, high specific capacity, high specific power, wide operating environment temperature, long storage time, rapid and reliable activation, and compact structure. It is an ideal military power supply. It is used in modern weapons (such as missiles, rockets, artillery, etc. ) are widely used. [0003] Dozens or even hundreds of subsystems of the weapon system have to go through multiple joint debugging tests and verifications before...
