On the electricity production and transmission, at present mainly based on alternating current (ac). Mains supply users is alternating current (ac), and on many occasions, such as electrolysis, storage battery charging, dc motor, etc., need to use direct current (dc). To get a direct current (dc), in addition to the direct current generator, the most common application is to use a variety of semiconductor devices produce direct current (dc). This method, the rectifier is the most basic step. Rectifier, it is using device with one-way conductive properties, convert direction and size of the alternating current to direct current (dc).
