+-12V直流稳压电源设计
设计一个直流稳压线性电源,输入220V,50Hz的正弦交流信号,输出±12V对称稳压直流电。 2.三端稳压器 三端稳压器,主要有两种,一种输出电压是固定的,称为固定输出三端稳压器,另一种输出电压是可调的,称为可调输出三端稳太器,其基本原理相同,均采用
Brush Electric Company''s central power plant with dynamos generating direct current to power arc lamps for public lighting in New York. Beginning operation in December 1880 at 133 West Twenty-Fifth Street, the high voltages it operated at allowed it to power a 2-mile (3.2 km) long circuit.
