20v 200a HF IGBT copper plating power supply with 220v 3 phase
input
Power supply rectification technology:
Plating power supply frequency is a direct current equipment of
changing industry frequency alternating voltage into different
voltage, frequency and waveform. In the thyristor rectifier main
application of “rectification” technology, while in the high
frequency switching mode power supply applying both “rectification”
technology and “inverter” technology.

How to install rectifier
This is installation way for remote control rectifier. Not only
this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power
supply/rectifier
4. We advice that all rectifiers should be isolated to increase of
its life.
Other advantages
1. Cabinet
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural
strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design,
rectification part is convenient to disassemble and mend because of
its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch
control, ensuring the lowest power loss of IGBT. The capacity of
IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight,
but also can strengthen rectifier stability and reliability. At its
elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and
the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported
lacquer.
