IGBT Based Power Supply for Single Crystal Silicon Ingot Grower Equipment

IGBT Based Power Supply for Single Crystal Silicon Ingot Grower Equipment

1. Single crystalsilicon grower power supply application 

Power supply for crystal growing furnace is for making single crystal silicon, single crystal silicon is widely used for PV solar power application. The power supply is to provide DC power supply for production of the silicon.
Use as single crystal grower furnace bottom heater power supply and side heater power supply, in inert gases, using graphite heater with high temperature to melt poly crystalline silicon material which was kept in quartz crucible; then put seed into silicon liquid and grow single crystal silicon by CZ process in accordance with automatic programs.

2. Single crystalsilicon grower IGBT power supply introduction
Over the past 20 years, Green Powerhas continuously developed its technology and has recognized internationally as high quality manufacturer in the field of crystal growth. The single crystal silicon grower IGBT based power supply replaces traditional SCR type power supply, has the advantages of power saving more than 20%, modular structure, high reliability, low power pollution to power grid, is widely applied in international PV applications.

4. Customer Benefitsof modular solution
Green Power has developed module based IGBT pulse rectifiers, which have the following advantages:Rectifier won't break down: in case of one module failed, the rectifier continue working with reduced power.

Less downtime and easy recovering:plug-in structure, replace module directly, downtime is shorten to minimum, this reduces potential high cost of your plant stop and increase your plant's availability.

Current expansion available:thanks to the modular design and supporting parallel connection, if you need more power, you only need to add more modules.

Reduce current rating to save power: if you don't need all modules working, you can switch off some modules, rectifier can work at lower rating.

Less floor space occupied: the rectifiers can be built on top of each other, making them easy to fit into your plant's design, optimizingfloor space.

Easy to install and maintain: each rectifier consists of up to ten modules and naturally two or more stacks can be connected to allow higher currents (40kA) and voltages (200V DC).

Separate output or parallel running output available: you can let the rectifier module separate output to connect to more tanks, or parallel connecting to get higher current for one tank.

5. Customer Benefitsof digital micro controller

• Consistent high stability in long time, not like analog control resistance and capacitor may change value causing control reliability reduce after some time.

• High control accuracy(up to 3/10000of max current or voltage)

• Protection self diagnosis and alarm protection type automatically on touch panel, easy for troubleshooting

• Timer counting, stop running when times up

• You can preset process curves, once you choose one process curve, the rectifiers auto run as per preset process curve.

• One process curve, you can set up to 20 steps (you define V or A value and step process time), auto running based

• Support soft start and soft stop time setting

• Fast responding speed

• Programmable, only reprogramming to DSP, don't need to change hardware like analog control

• Smart communication with PLC, RS485, Profibus, Profinet communication optional, 4-20mA/0-10V signal

• Adapt to different load
