I. Product Introduction
As a DC voltage-regulating control power supply, the DC switching power supply for solar silicon single-crystal furnace adopts DSP and CPLD as the control core, IGBT as the power inverting device and high-frequency ultracrystalline transformer as the load-matching transformer. Adopting fast diode full-wave rectification, it realizes continuously adjustable output power by the phase controlled regulation way. In the entire inverting work process, by adopting high-precision power closed-loop control and LCC quasi-resonant mode, it realizes IGBT soft switching and reduces the switching losses of IGBT as well as the electromagnetic emission and conducted interference generated by the power supply to the outside world, what¨s more, its multiple given signal selection functions and isolated conversion & output of output DC voltage, current and power facilitate the remote monitoring of PLC and host computer. For the power supply, the conversion efficiency is higher than 0.92, the power factor is more than 0.97, the total harmonic wave of current is less than 13% and the direct-current output frequency is 50 KHz, with smooth direct current, it reduces the electromagnetic disturbance to the silicon liquid level, so it is really a new generation of ideal power supply substituting for SCR bridge rectification and double reverse-stars type rectification power supply.
II. Performance Indexes
1. It adopts cabinet-type integrated design.
2. It adopts IGBT as the power inverting device with the inverting work frequency of 25KHz and ultracrystalline alloy transformer and it is characterized by small size, light weight, low losses, low cost and no noise within the audibility range.
3. With high-precision AD conversion, the constant power precision is higher than 1°.
4. It has phase-deficient, overcurrent, overheating, cooling water fault protection and inverting fault protection functions as well as fault self-diagnosis function.
5. It has soft start and soft turn-off functions which reduce |
