Abstract

The invention discloses a self-unlocking power conversion circuit, which comprises a thermal battery powering switch and the like, wherein a third sampling resistor and a first reference source are connected with a positive electrode input end of a first logic judgment operational amplifier, an output end of the first logic judgment operational amplifier is connected with the thermal battery powering switch, a first sampling resistor and a second sampling resistor, the first sampling resistor is connected in series with the second sampling resistor, the third sampling resistor is connected with the first reference source, a fourth sampling resistor is connected with a second reference source, and the fourth sampling resistor and the second reference source are both connected with a negative electrode input end of a second logic judgment operational amplifier. The self-unlocking power conversion circuit can effectively prevent a missile thermal battery from affecting operation of a carrier power supply during the activation process of the thermal battery when the carrier power supply and the missile thermal battery are in a grid-connected power supply state, and can prevent the problem of reliable output of the thermal battery after the thermal battery is activated.

Description

technical field [0001] The invention relates to the field of electric power supplies, in particular to a self-unlocking power conversion circuit. Background technique [0002] At present, the air-to-air missile interface mainly implements GJB 1188A-99 "Interface Requirements for Aircraft / Suspension Electrical Connection System", and the air-to-air missile power supply standard mainly implements GJB 1019A-2006 "General Specifications for Air-to-Air Missile Power Supply". According to the interface requirements of the task hanger stipulated in the above-mentioned standards, the air-to-air missile is powered by the on-board DC power supply to the equipment on the missile when it is on-hook. After the missile is launched, the on-board thermal battery supplies power to the on-board equipment. The thermal battery is a molten salt chemical power source used for one-time activation. It uses the heating system of the battery itself to heat and melt the non-conductive solid salt elec...
