設(shè)計(jì)功率MOSFET驅(qū)動電路時(shí)需重點(diǎn)考慮寄生參數(shù)對電路的影響。米勒電容作為MOSFET器件的一項(xiàng)重要參數(shù),在驅(qū)動電路的設(shè)計(jì)時(shí)需要重點(diǎn)關(guān)注。重點(diǎn)觀察了MOSFET的開通和關(guān)斷過程中柵極電壓、漏源極電壓和漏源極電流的變化過程,并分析了米勒電容、寄生電感等寄生參數(shù)對漏源極電壓和漏源極電流的影響。分析了柵極電壓在米勒平臺附近產(chǎn)生振蕩的原因,并提出了抑制措施,對功率MOSFET的驅(qū)動設(shè)計(jì)具有一定的指導(dǎo)意義。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
