这个IGBT驱动电路有何不足吗？: [size=4][color=#0000ff][b][color=royalblue]这是一个有刷直流电机的驱动电路，电机是DC 220V/10A的，用的是IGBTG40N60作为驱动，通过单片机PWM控制33152驱动40N60，最近老是发现驱动管击穿的现象（GCE都击穿了，估计是烧的一踏糊涂）。看了很多资料，有的上面说要加RCD缓冲电路，还有说驱动最好用15V电压的。电路如下图所示：[/col...; 小鱼儿1045 工控电子

跪求高手指点CYCLONE 片内RAM读写问题: 小弟新手，最近使用CYCLONE IV的片内RAM,双口，一口写，一个口读，深度512，位宽16bit，我的操作时线写512*16bit，再读512*16bit，就不存在读写地址相同的情形现在问题是我读出来的数据全是0，不知道是没有写进去，还是没有读出来，时序貌似没有问题啊，跪求高手指点，附上我的singaltap波形，...; mc516 FPGA/CPLD
