Problems solved by technology

The voltage regulator installed on a vehicle using a 1.2W ordinary light bulb or LED lamp cannot sufficiently flow in the required current at the initial stage of conduction, so there is a problem that the RPM of the car alternator increases, causing the car to generate electricity The machine cannot generate electricity normally
In order to solve this problem, the vehicle factory usually connects resistors in parallel at both ends of the vehicle charging indicator light, which makes the circuit structure more complicated and adds more processes to the vehicle factory.

Wherein, it comprises power anode, generating instruction lamp wiring terminal, generator winding wiring terminal, and ground end; the generating instruction lamp wiring terminal is connected to sampling circuit; the generator winding wiring terminal and the ground end have switch circuit between them; the output of sampling is connected to the input of switch circuit. The invention is characterized in that: there are current amplifiers between the instruction lamp wiring terminal, the power anode and the generator winding wiring terminal. The invention has simple structure and wide application.

Description

technical field [0001] In particular, the invention relates to automotive alternator voltage regulators. Background technique [0002] When an automotive alternator is initially started, the generating current is input through the vehicle charging indicator terminal. In the past, vehicle charging indicators generally used light bulbs with a power of more than 3W. Recently, more cars use LED tubes. The voltage regulator installed on a vehicle using a 1.2W ordinary light bulb or LED lamp cannot sufficiently flow in the required current at the initial stage of conduction, so there is a problem that the RPM of the car alternator increases, causing the car to generate electricity The machine cannot generate electricity normally. In order to solve this problem, the vehicle manufacturers generally connect resistors in parallel at both ends of the vehicle charging indicator light, which complicates the circuit structure and increases the process for the vehicle factory.
