Means for transformer rectifier unit regulation

摘要: Transformer rectifier units (TRU) for the conversion of AC to regulated DC are disclosed. One aspect a TRU according invention is output boost regulation by monitoring from conventional TRU, and when drops below 28 volts an additional electronic switching converter boosts up volt level. Under overload conditions bypass diode returns operation that maintain required high current. Another aspect, input buck regulation, regulates controlling impedance auxiliary transferring its via flyback converter.
