Photovoltaic PECVD RF power supply (dual output)

Techanical features:

★It has built-in lightning arrester and surge protector double protection, FC passive filter device + EMI filter, get green energy power supply

★Its main circuit topology adopts PFC + the world's latest generation of Sic and IGBT combined full-bridge structure, combined with DSP + FPGA digital control technology, which greatly reduces the risk of failure. Compared with the old generation of Si-MOSET, the reliability of the new generation of Sic-MOSET power supply should be improved. 12 times, 4 times higher thermal conductivity

★We simplify the main circuit topology, reduce the complexity of heat dissipation design and installation, reduce the risk of potential failure, and improve the reliability of the product

★ Its power transformer adopts nanocrystalline magnetic core material    It has extremely high magnetic permeability, high saturation magnetic induction intensity, low coercivity, low loss, wide frequency characteristics, high magnetic permeability at 30MHz, small magnetic leakage, small size, easy winding, pressure  resistance and easy control, and failure risk <1

★ Arc suppression management     Detect abnormal voltage within ＜300ns (OUT > 20% of reference)     When I-Arc occurs, it can cut off and restart the power within 10ms     When V-Arc occurs, voltage control adjustment starts within <5μs     Residual Arc energy is less than 1mJ/kW, which can eliminate the problem of stuck points, thereby improving product yield and efficiency

★ Its main power module adopts pure copper plate large water cooling system + auxiliary air cooling structure designIt has multiple temperature control sensors for monitoring and protection. Compared with imported products, the temperature is 4 to 6 degrees lower
