Full-Wave or Half-Wave Power Supplies
... Full-wave power supplies take power during both halves of the AC waveform. BAPI’s PS17 and PS17CB are full-wave power supplies. The VC2700-STM and VC3000 are available as full-wave or half-wave (specified at time of order). Transformers used in full-wave power supplies cannot have either of their ou ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
