air cooling IGBT type 24V 3000A Electro Polishing Power Supply rectifier
1. The basic principle of periodic reverse pulse plating
In the pulse plating process, when the current is turned on, the
electrochemical polarization increases, the metal ions near the
cathode area are fully deposited, and the plating layer is finely
crystallized and bright; when the current is turned off, the
discharge ions near the cathode area return to the initial
concentration. The concentration polarization is eliminated.
Periodic commutation pulse plating is commonly known as double (ie
bidirectional) pulse plating. It introduces a set of reverse pulse
current after outputting a set of forward pulse current. The
forward pulse duration is long and the reverse pulse duration is
short. The highly non-uniform anode current distribution caused by
the short-time reverse pulse will cause the convex part of the
coating to be strongly dissolved and flattened. The typical
periodic commutation pulse waveform is shown below.
Features
Using timing control function, the setting is simple and
convenient, and the working time of positive and negative current
polarity can be arbitrarily set according to the plating process
requirements.
It has three working states of automatic cycle commutation,
positive and negative, and reverse, and can automatically change
the polarity of the output current.
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.
High frequency switching rectifier, also called switching power
supply
A new type of electroplating power supply equipment-high-frequency
switching power supply. It combines the advantages of the waveform
smoothness of silicon rectifiers and the convenience of voltage
regulation of silicon-controlled rectifiers. It has the highest
current efficiency (up to 90% or more) and the smallest volume. It
is a promising rectifier. The manufacturing technology has solved
the power problem, and the high-power switching power supply from
thousands of amps to tens of thousands of amps has entered the
practical stage of production.
It directly rectifies and filters the AC power grid through the EMI
anti-electromagnetic interference line filter, converts the DC
voltage into a high-frequency square wave of tens or hundreds of
kHz through the converter, isolates and reduces the voltage through
the high-frequency transformer, and then through the high Frequency
filtering output DC voltage. After sampling, comparing, amplifying
and controlling, driving circuit, the duty ratio of the power tube
in the converter is controlled to obtain a stable output voltage
(or output current).
The adjustment tube of the high-frequency switching rectifier works
in the switching state, the power loss is small, the efficiency can
reach 75% to 90%, the volume is small, the weight is light, and the
accuracy and ripple coefficient are better than the silicon
rectifier, which can be in the full output range. Achieve the
precision required by production. It has self-protection ability
and can start and stop arbitrarily under load. It can be easily
connected with a computer, which brings great convenience to
automated production and is widely used in the PCB plating
industry.
