Description

Multi-functional charger

The utility model relates to a kind of device that is used for batteries charging, particularly has the device to batteries charging, starter motor motor vehicle engine and three kinds of functions of electric welding.

It is 90226814.7 locomotive charge initiation double-purpose electric source that China's utility model patent discloses a kind of application number, and it is made up of charging circuit unit and start-up circuit unit two parts.The start-up circuit unit is by main coil, iron core and actuating coil and diode D ₇Form.Its deficiency is: the start-up circuit unit adopts diode D ₇Carry out halfwave rectifier, the direct current fluctuation of output is bigger, and motor car engine is had certain influence; Startup and charging circuit are only exported a kind of magnitude of voltage, have limited the scope of application; This power supply does not have other function.

The purpose of this utility model is to provide a kind of to be had charging, starter motor motor-car and welds the multi-functional charger that the output voltage of three kinds of functions and charging and start-up circuit can be regulated.

Technical solution of the present utility model is: multi-functional charger comprises charging circuit, start-up circuit, transformer, its special character is that the transformer secondary output winding is made up of the segmentation winding that has tap, and by start and battery charging switch respectively with one or two or more segmentations around to being serially connected in start-up circuit and the charging circuit, formation can be exported the startup and the charge circuit of two or more voltage.To satisfy the requirement of dissimilar engines and storage battery, enlarge its scope of application.

Multi-functional charger also comprises an electric welding loop, it by be wound on respectively on two iron core column of transformer and mutually the secondary winding of serial connection constitute and exchange the electric welding loop or by being wound on two iron core column of transformer respectively and the secondary winding and the coupled rectification circuit of serial connection constitute the direct-current electric welding loop mutually.In order to reduce leakage field, reduce the wastage, the primary winding will be wound on respectively on two iron core column by certain turn ratio.

Described start-up circuit is all-wave or bridge rectifier, and its input is connected with one of transformer secondary output or two or more segmentation windings with the transformer secondary output winding or through starting change over switch.

Characteristics compared with prior art of the present utility model are: have startup, charging, three kinds of functions of welding, a tractor serves several purposes; Charging and the output voltage that starts the loop can be regulated, and promptly can export 12 volts, 24 volts or other amount of voltage value, with the storage battery that satisfies different capabilities and the requirement of engine, have enlarged the scope of application; Start-up circuit adopts full-wave rectification, and it can export direct current more stably; This machine not only starts easily as starting power supply, not influenced by cryogenic conditions, and saves storage battery; These machine materials are economized, cost is low, utilance is high, are particularly suitable for small-sized maintenance station and family and use.
