Diode bridge is well-known term at the electronics market, however the purpose of this particle may not be so clear to everybody. Let´s take a peek at a general description! The primary function of single-phase diode bridge is to convert alternating current to direct curent, that is why they are often called „bridge rectifiers“. 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 and patented in December 1895 in Great Britain and in January 1896 in Germany. Nevertheless Leo Graetz indepentelly invented the same circuit in 1897. That is why you can also find a name of this particle as „Graetz bridge“.
Diode bridge by MDD feature high-end quality and great realiability. These particles can be distinguished by its case, voltage range and current.
Basic types of single-phase diode bridges:
Vrrm = (20-1000)V Iao = (0,5 – 5)A
Vrrm = (50-1000)V Iao = (6 – 50)A
Vrrm = (50-1000)V Iao = (1 – 2)A
Vrrm = (50-1000)V Iao = (2 – 35)A
