rectifier stack[′rek·tə‚fī·ər ‚stak]
a semiconductor instrument made up of an assembly of sequentially connected rectifier semiconductor diodes.
Several rectifier stacks contained within a single housing make up a rectifier unit, which may be switched into electrical circuits according to various schemes. Rectifier stacks and units are utilized in various radio-electronic and electrical-engineering instruments and installations to rectify alternating current of industrial and audio frequencies. The rectifier stacks being produced by domestic industry (in 1969) allow an amplitude of inverse voltage of up to 2 kilovolts (kV) at a rectified current of up to 300 milliamperes (mA) and up to 10 kV at a current of up to 50 mA, whereas rectifier units allow 500 V at 400 mA.
