The rectifier bridge is to seal the rectifier tube in a shell. Full bridge and half bridge. The full bridge is the four diodes of the bridge rectifier circuit that are connected together. Half bridge is the four diode bridge rectifier half sealed together, with two half bridge can form a bridge rectifier circuit, a half bridge can also be composed of transformer with center tap full-wave rectifier circuit, choose rectifier bridge to consider the rectifier circuit and working voltage.

Rectifier bridge is generally used in full-wave rectifier circuit, it is divided into full bridge and half bridge.

The full bridge is composed of 4 rectifier diodes connected and packaged as a whole in the form of a bridge full-wave rectifier circuit. The figure shows its appearance.

The forward current of the full bridge has various specifications such as 0.5A, 1A, 1.5A, 2A, 2.5A, 3A, 5A, 10A, 20A, 35A, 50A, etc. The withstand voltage (highest reverse voltage) has various specifications such as 25V, 50V, 100V, 200V, 300V, 400V, 500V, 600V, 800V, 1000V, etc.

The rectifier circuit and the operating voltage should be considered when selecting the rectifier bridge. Rectifier bridge is generally used in full-wave rectifier circuit, it is divided into full bridge and half bridge.

Functional characteristics of the generator

The voltage change rate of the synchronous generator is about 20-40%. General industrial and household loads require that the voltage remain essentially constant. For this reason, as the load current increases, the excitation current must be adjusted accordingly. Although the trend of the adjustment characteristics is the opposite of the external characteristics, it rises for inductive and purely resistive loads, and generally decreases under capacitive loads.

Car fuel injector oil leakage will cause the engine to idle?

Oil leakage from the fuel injector of a car will cause the engine to tremble at idling speed, and the gasoline dripping into the cylinder will make the mixture too rich, and the mixture too rich will cause difficulty in starting the engine. If the fuel injection nozzle carbon deposition is more serious, may lead to a slight drip phenomenon. Car friends can add additives that can remove carbon deposits to the fuel tank when refueling, so that the carbon deposits on the fuel injector can be removed.
