12Volt 7000Amp high power igbt water cooling plating rectiifer main technical characteristics:
Switch mode power supply working principle:
Principle of Switch mode power supply control regulator for voltage
stabilization:
Switch knob turn on and off repeatedly to a certain time interval,
when the switch is turned on, the input power supply through switch
knob and filter circuit to supply loading, during the entire switch
turn on duration, the power supply provided energy to loading;
When switch disconnected, input power supply interrupted to provide
energy. Be seen, the input power supply to provide energy for load
is intermittent, in order to load can be obtain a continuous energy
power supply, switching mode power supply must have a energy
storage device, when the switch turns on, there is a part of energy
stored in the switch, when disconnect, the stored energy will
release to load. Inductance used to store energy, when the switch
is off, stored energy in the inductance through the diode release
to the load, make sure that the load to obtain a continuous and
stable energy, because the diode enable load to get continuous
current, so called continuous current diodes. This is the way
switch mode power supply working.

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.
