The invention provides a voltage-stabilizing and filtering device for the vehicle voltage. The device comprises a voltage reducing and filtering circuit, a voltage stabilizing and filtering boost circuit, a dummy load filtering circuit and a control circuit. The voltage reducing and filtering circuit is used for reducing the output voltage generated by a power generator. The voltage stabilizing and filtering boost circuit is used for carrying out voltage stabilization and filtering on the voltage after voltage reduction and then boosting the voltage. The dummy load filtering circuit is used for filtering and dispersing a pulse ripple and a distorted micro-impurity signal source existing in the boosted voltage. When the control circuit is switched to be turned on, the voltage of the dummy load filtering circuit is supplied to an electronic element to serve as the working voltage. When the control circuit is switched to be turned off, the dummy load filtering circuit serves as the load of a second voltage. In this way, the residual voltage can be discharged when a vehicle engine is turned off and the generator stops running. Therefore, the device of the invention is formed. A voltagesignal transmitted by the electronic element can be ensured to be stable and correct.
Description
technical field [0001] The invention relates to a voltage stabilizing filter device, in particular to a voltage stabilizing filter device for vehicle voltage. Background technique [0002] The control circuits used in automobiles are composed of electronic components connected in series, parallel and hybrid circuits. The control circuits used in automobiles have various types of control, roughly including the control of engine ignition, instrumentation signals, interior air conditioning, lighting, and battery charging. [0003] The power consumption required by the aforementioned control circuit is driven by the engine of the car, such as image 3 A generator 91 is shown in operation, generating electricity that is supplied to electronic components 92 and stored by a battery 93 . However, generators often have excessive distortion of the output voltage signal due to factors such as impurities contained in the production of enameled coils, variable quality coefficient voids,...
