DC Components GBK25M 1~ full bridge rectifier bridge, 1000V 25A *new*

A diode bridge is an arrangement of four (or more) diodes in a bridge circuit configuration that provides the same polarity of output for either polarity of input. When used in its most common application, for conversion of an alternating-current (AC) input into a direct-current (DC) output, it is known as a bridge rectifier. A bridge rectifier provides full-wave rectification from a two-wire AC input. The essential feature of a diode bridge is that the polarity of the output is the same regardless of the polarity at the input. The diode bridge circuit was invented by Polish electrotechnician Karol Pollak. The German physicist Leo Graetz independently invented and published a similar circuit. Today the circuit is sometimes referred to as a Graetz circuit or Graetz bridge.
