Rectifier Transformer
A transformer designed to supply rectifier/inverter loads with enhanced harmonic and DC magnetization handling.
A rectifier transformer supplies AC-to-DC rectifier circuits. Used in electrochemical processes, HVDC, VSDs, renewable energy.
Challenges: harmonic currents causing eddy losses, DC magnetization causing core saturation. Features: increased kVA (derating), phase-shifting windings (12/18/24-pulse), enhanced cooling, shields.
