Controllable silicon closing time prolonging control technology for motorcycle fuel saving rectifier

Abstract

The invention discloses a controllable silicon closing time prolonging control technology for a motorcycle fuel saving rectifier. The controllable silicon closing time prolonging control technology consists of a controllable rectifying part and a voltage stabilizing part, and is characterized in that the controllable rectifying part mainly comprises controllable silicon and a rectifying diode. When the voltage of a storage battery is up to the break-over voltage set by the voltage stabilizing part, the voltage of the control pole of the controllable silicon is reset, and the output current of the controllable rectifying part falls rapidly to a voltage stabilizing state; and if an electrical appliance is loaded at the moment, the voltage of the storage battery falls, the voltage at the control pole of the controllable silicon starts to rise, electric energy is absorbed by a delay capacitor, and the time of voltage rise is prolonged by 30 percent, so that the closing time of the controllable silicon is prolonged effectively, and the switching speed of the controllable silicon is lowered. Due to the adoption of the controllable silicon closing time prolonging control technology, the effect of prolonging the closing time of the anode and cathode of the controllable silicon is achieved, the overall temperature is lowered, and the engine fuel oil waste is reduced.

technical field [0001] The invention relates to a technology for controlling the switching time of a silicon controlled rectifier in a rectifying and charging part of a motor vehicle, in particular to a technology for extending the closing time of a silicon controlled rectifier for a motorcycle fuel-saving rectifier. Background technique [0002] Motorcycles generally adopt the short-circuit voltage stabilization method. This structure is simple, but the load of the magneto is large, and all the excessive voltage of the generator leaks from the ground wire, causing the temperature of the thyristor to be too high. Secondly, in order to overcome the load of the magneto The magnetic cutting force will inevitably cause unnecessary waste of fuel; and as a switch-controlled rectifier, although it has the function of disconnecting the connection between the magneto and the rectifier at full power, the instantaneous high voltage generated when it is disconnected and combined is easy...

[0002] Motorcycles generally adopt the short-circuit voltage stabilization method. This structure is simple, but the load of the magneto is large, and all the excessive voltage of the generator leaks from the ground wire, causing the temperature of the thyristor to be too high. Secondly, in order to overcome the load of the magneto The magnetic cutting force will inevitably cause unnecessary waste of fuel; and as a switch-controlled rectifier, although it has the function of disconnecting the connection between the magneto and the rectifier at full power, the instantaneous high voltage generated when it is disconnected and combined is easy to cause The thyristor burns out, and at the same time, the turn-on time of the thyristor is too fast, and the service life of the thyristor is greatly reduced
