Pulse-controlled silicon controlled rectifier floating charger

Abstract

A pulse-controlled silicon controlled rectifier (SCR) floating charger belongs to the technical field of electronics. The pulse-controlled SCR floating charger is composed of a trickle resistor, a constant current unit, an SCR charging unit, an SCR pulse unit, a voltage stabilizing unit of an integrated circuit, a counting unit, an end unit, a charging display unit, an end sound unit and a load unit. A three-terminal voltage regulator is connected in a constant-current mode, and thus, a constant current can be provided for the SCR charging unit. The SCR charging unit is controlled by the SCR pulse unit. Therefore, a pulse type constant-current charging process is formed. When the timing in the counting unit ends, the end sound unit sends out a sound prompt, the end unit is started, the SCRcharging unit is clamped to stop charging, the charging display unit stops display, the oscillation in the counting unit stops until the artificial end, and the trickle resistor provides a maintaining trickle current for a charged battery. The units are connected scientically. Comprehensive utilization is achieved. The pulse-controlled SCR floating charger is easy to produce and debug, and is very suitable for micro enterprises.

[0002] With the enrichment of modern life, there are more and more types of electrical appliances using batteries, such as security equipment, digital machines, mobile phones, etc. For this reason, there are also many types of chargers, but there is a lack of a low-carbon battery in these types. Various types of environmentally friendly charging circuits

The first significance is that the charging supervisor in the current product is the circuit transistor that stops charging and is easily damaged. Once damaged, the charger becomes garbage.

It is understood that this failure has become the main failure point, and it is a great waste to turn it into garbage just because of this damage. People are often lost)

The second significance is that during the charging process, the battery is not charged scientifically, so it affects the capacity and life of the battery. It is also easy to turn the battery into garbage prematurely, which forms waste and pollutes the environment

(Waste batteries pollute the environment)

The reason for not achieving the most scientific charging is that the current products either only use DC to charge the battery, but do not use a better method, such as constant current charging; or even though they can be charged with a constant current source , but there are still some conveniences in use, or it is not scientific enough on the line, etc., so it should be enriched and developed
