400W 3-phase input industrial fan motor drive
此參考設計?案是專為單相輸?的?機驅動轉為三相輸?設計。 單相輸?時,?機驅動?線電壓為400V。為適配三相輸?,將三相AC輸??先升壓?700Vdc,再將700Vdc降壓?400Vdc。三相PFC和Buck變換器由?顆MCU控制,?機驅動由另?顆MCU控制。三相PFC實現了10%負載時,iTHD在20%以內的設計要求。
400A high frequency robot welding machine
本參考設計?案是?頻逆變式機器?焊接電源,采?DSC微處理器,實現全數字控制,額定電流為350A. 主電路采?基于SiC器件的硬開關全橋?案。電路簡單,使??研SiC驅動模塊,實現有源密勒鉗位和去飽和短路保護功能,提?了系統的可靠性。
16KW HVAC solution base on SiC device
This solution used Wolfspeed's SiC devices to instead of traditionaIGBT module for HVAC systems, which can significantly improve thesystem performance and has more cost effective. The compressorcontrol frequency was set to 16KHz to reduces audible noise.Meanwhile, the system efficiency is much higher compared withtraditional IGBT devices, especially with light load. The standby powerconsumption is lower to meet the standby energy efficiency standard
