Abstract

The invention discloses a non-polarity safe charger circuit which is composed of a live line and zero line identification circuit, a resistor-capacitor (RC) phase shift trigger circuit, a silicon controlled charging circuit and a polarity identification circuit, wherein the live line and zero line identification circuit can be used for identifying a live line and a zero line at an input end of an alternating current; the live line at the input end of the alternating current is connected to an input end of the silicon controlled charging circuit, so that the live line is not directly connected with the polarity output end; the zero line is directly connected with the polarity output end through a switch, so that the security coefficient is improved; the size of charging current of the silicon controlled charging circuit is controlled by the RC phase shift trigger circuit; the size of the charging current is adjusted; and operation of the RC phase shift trigger circuit or the live line and zero line identification circuit is controlled by the polarity identification circuit, so that the silicon controlled charging circuit charges according to the correct storage battery polarity, the storage battery or the charger cannot be burned, and the non-polarity safe charger circuit is safe and reliable.

Description

technical field [0001] The invention relates to a charger, in particular to a non-polarity safety charger circuit. Background technique [0002] At present, there are many types of chargers in the prior art, but they all have a common feature, that is, they must be connected according to the correct polarity of the battery, and the output terminal of the charger cannot be short-circuited, otherwise the battery or charger will be burned, and a fire may be caused in severe cases. . [0003] Moreover, the number of batteries charged by most chargers is very small, and the current size cannot be adjusted; the live wire and neutral wire cannot be automatically identified, and the safety factor is low. Contents of the invention [0004] The invention provides a non-polarity safety charger circuit, which can automatically identify and switch the polarity, the magnitude of the current is adjustable, the live wire and the neutral wire can be automatically identified and switched, ...
