设计功率MOSFET驱动电路时需重点考虑寄生参数对电路的影响。米勒电容作为MOSFET器件的一项重要参数,在驱动电路的设计时需要重点关注。重点观察了MOSFET的开通和关断过程中栅极电压、漏源极电压和漏源极电流的变化过程,并分析了米勒电容、寄生电感等寄生参数对漏源极电压和漏源极电流的影响。分析了栅极电压在米勒平台附近产生振荡的原因,并提出了抑制措施,对功率MOSFET的驱动设计具有一定的指导意义。When designing the drive circuit of power MOSFET,the influence of parasitic parameters on the circuit Should be concerned.As an important parameter of MOSFET device,Miller capacitance Should be considered in the design of drive circuit.The variation of gate voltage,drain source voltage and drain source current during the turn-on and turn-off of MOSFET were observed.The influences of parasitic parameters such as Miller capacitance and parasitic inductance on drain source voltage and drain source current were analyzed.The reasons of gate voltage oscillation nearby Miller plateau were analyzed,and the restraining measures were put forward.This research was instructive for the drive design of power MOSFET.

If register Should be written or read.This value is passed to the calback functions which support either reading or writing register values. Writing means that the application registers Should be updated and reading means that the modbus protocol stack needs to know the current register values.See also: eMBRegHoldingCB(), eMBRegCoilsCB(), eMBRegDiscreteCB() and eMBReglnputCB().Enumeration values: MB_REG_READ Read register values and pass to protocol stack.MB_REG_WRITE Update register values.Note: Note all ports implement this function.A port which wants to get an callback must define the macro MB_PORT_HAS_CLOSE to 1.Returns: If the resources where released it return eMBErrorCode:: MB_ENOERR. If the protocol stack is not in the disabled state it returns eMBErrorCode:: MB_EILLSTATE.Examples: LINUX/demo.c, MCF5235TCP/demo.c, STR71XTCP/demo.c, WIN32/demo. cpp, and WIN32TCP/demo. cpp.his function disables processing of Modbus frames.Returns: If the protocol stack has been disabled

German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you Should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence
