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。
150A hybrid bidirectional solid state relay
This product is a high performance & low cost bi-directional hybridrelay designed by mixing a high power IGBT and a traditionamechanical relay. The maximum rating is 800V/150 A. Like traditionalmechanical relays, this product supports 2500 Vrms isolation and canbe widely used in electric vehicles, charging piles, energy storage, PVinverter, etc.
The project is a 3.6kW bitcoin miner power supply with input 90-264Vacand output 12V300A. SiC-based totem-pole PFC and interleaved parallelsynchronous rectifier LLC topology were selected for system design. Thetotem pole PFC achieve extremely high efficiency (peak up to 99%) andthe interleaved synchronous LLC reduce output current ripple from 48%to 12% which greatly reducing output capacitor stress.
800W Platinum Efficiency Server Power
This reference design provides a low-cost server power solution. Thesystem is designed with PFC and synchronous rectifier LLC topologyusing a single Spintrol ARM4 MCU SPC1168 to control both the PFCand LLC. This solution achieves the requirements of platinumefficiency and standby power consumption standard, meets the iTHDdynamic and current sharing design requirements of full load range.which is a highly completed server power reference solution.
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
