SINGLE PHASE INPUT - 3 PHASE OUTPUT TRANSFORMER HAVING ELECTROSTATIC SHIELD

摘要

PURPOSE: A single input-three phase output electrostatic shield transformer is provided to obtain DC with low ripple by full-wave rectifying three phase output. CONSTITUTION: A core(100) has first to third pillars(101-103). A primary coil, an electrolytic shield electrode, a first secondary coil and a second secondary coil of a first transformer are successively wound around the first pillar. The primary coil, the electrolytic shield electrode, the first secondary coil, and the second secondary coil of the second transformer are successively wound around the third pillar. A phase change capacitor is serially connected to the primary coil wound around the third pillar.
