Portable electrifying, charging and discharging equipment for photoelectric device

Abstract

The invention relates to an electrifying, charging and discharging equipment for a portable photoelectric instrument, which comprises parts including a DC / AC inverter circuit, a first rectification filter circuit, a passive PFC (Power Factor Correction) circuit, a DC / DC conversion circuit, a PWM (pulse-width modulation) circuit, a second rectification filter circuit, an electrifying circuit, a singlechip control circuit, an operation display circuit, a discharge circuit, a protection circuit and the like. The portable electrifying, charging and discharging equipment for the photoelectric instrument is mainly used for the electrifying maintenance to various portable photoelectric instruments, and charging and discharging to nickel cadmium batteries, nickel-hydrogen batteries and lithium batteries used together with the photoelectric instruments, can organically integrate the main functions of stabilized voltage supplies and charging equipment, and integrates the functions of electrifying, battery charging and discharging and the like of the instruments. Therefore, the integration degree of support equipment for the portable photoelectric instruments is greatly improved.

Description

technical field [0001] The invention relates to a power conversion device for converting direct current or alternating current power input into direct current power output, in particular to a power supply and charging and discharging device for portable photoelectric instruments. Background technique [0002] Portable optoelectronic instruments mainly include low-light night vision devices, laser range finders, and thermal imaging cameras, etc., which are optoelectronic instruments used to perform functions such as observation, measurement, and aiming. The batteries used in such optoelectronic instruments are generally nickel-cadmium, nickel-metal hydride, lithium batteries, etc. When the battery power is exhausted, the charger needs to be used to charge the battery; when the battery is damaged, an external regulated power supply should be used to provide the rated voltage required for the operation of the portable photoelectric instrument. [0003] In order to ensure the n...
