Student-MFC-VCPP-ODBC
用MFC做的一个学生信息管理系统，有增加、删除、排序、筛选功能，系统通过ODBC方式连接数据库。
由于文库不支持RAR，故需要完整的程序以及数据库可以联系俺，希望对大家有帮助。
(To do with the MFC, a student information management system, increase, delete, sort, filter functions, the system through ODBC to connect to the database. The library does not support RAR, I therefore need to complete the program and database can be contacted, we hope to help.)

In higher power applications to utilize the full line power and reduce line current harmonics PFC
Pre-regulators are generally required. In these high power applications interleaving PFC stages can
reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall
magnetic volume and filter capacitor volume increasing the converters overall power density. This is made
possible through distributing the power over two interleaved boost converters and the inductor ripple
current cancellation that occurs with interleaving, reference [5]. This application note will review the design
of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T
