Abstract

The invention discloses a soft-start circuit and a soft-start voltage regulator applying the same. The soft-start circuit is composed of an active component and a passive element. The soft-start voltage regulator is electrically connected with an electric generator, a battery pack and a starter. When the starter is started, the soft-start voltage regulator receives voltages of the battery pack to generate soft-start signals, and the electric generator generates voltages according to the soft-start signals. In addition, after the voltages are generated by the electric generator, the soft-start signals output by the soft-start voltage regulator are interrupted.

Description

technical field [0001] The invention relates to a voltage regulator applied to a vehicle, in particular to a soft start circuit composed of an active element and a passive element, a soft start voltage regulator using the soft start circuit and a system thereof. Background technique [0002] The electric energy required for the operation of the car is supplied by the generator. When the generator has not started to run, the stator (stator) and the excitation coil in the generator have no current and no power generation. It is necessary to provide current to the excitation coil to make the stator move and then Make the generator generate electricity. The generator excitation current source and control method can be realized through a pre-excitation circuit. Some pre-excitation circuits include an excitation diode (triodode), and some do not include an excitation diode. Contains exciter diodes (triodiodes), such as figure 1 As shown, before the generator is not running, the ...
