【实例简介】MQTT 协议+W5500EVB+DHT11模拟实现了手机端可以在外网控制板载LED 灯的亮灭和实时接收 DHT11 采集到的数据，其中 W5500EVB 作为以太网网关，负责将采集 到的温湿度数据加上设定的主题按照 MQTT 协议的要求 PO 到 MQTT 云端，或者在订阅针 对 LED 灯开关控制的主题后从 MQTT 云端接收手机 APP 发过来的对应 LED 灯开关控制的 主题的控制指令。当然，现实的话大神们可以脑补一下用带有蓝牙或者 Zigbee 控制功能的 灯泡或家电设备，开发板这边也加上接收模块…这是后续需要完善的，手机 APP 怎么做的 下次有机会再讲，这次先把 MQTT 以太网网关怎么实现的，以及如何采集 DHT11 数据等方 法给大伙儿分享下。

这是参加省赛的程序，用SCL语言编写的，当时学校生产实习没有时间详细做，所以说做的比较仓促，无缘国赛，不过也得了省一还是很不错的，期望拿到程序的你可以完善我没有做完的智能群控调度算法，明年国赛战出成绩，加油

在电力电子装置中的一个重要组成部分,输入连接到控制电路的PWM信号输出端，输出连接到装置各IGBT的门极和发射极，将装置中的控制电路产生的数字PWM信号进行隔离传输和电平转换和功率放大,实现控制电路对IGBT进行开通和关断动作的控制，从而实现装置的功率变换功能。InfineontechnologiesIGBT Gate Drive: Power Suppliesa Gate driving voltage for IGBT+15Vturn-on is normally +15VDriver>□1a Gate driving voltage for IGBTOVturn-off can be oV or negativeWith Single Power Supply5V to-15V)a Negative gate driving voltage+15Vhelps IGBt switch off fasterremain in off state but itDriverneeds dual power suppliesOVWhether to use oV or negativegate driving voltage depends15VWith Dual Power Supplieson the requirement on costZH Liang - Al APperformance05Dec2003agefor internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive: InterfaceOpto-couplers is commonly used as interfacingdevices for applications where both signaltransmission and potential isolation are requiredOpto-couplers offers reliable isolation between IGBT(high-potential)& micro-controller(low-potential)Opto-couplers has long signal delay(us)and isexpensiveIsolation +VDpCCMicroDrivercontrollerZH Liang - Al AP05Dec2003Page 6for internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive: Half-bridge DriveStandard configuration: 2 drivers, 2 power supplies, 2 opto-couplersAdvantages: standard, reliableDisadvantages: using opto-couplers, higher system costIsolation +VDDlCC1DriverCC1MicrocontrollerDD2+VCC2DriverCC2ZH Liang - Al AP05Dec2003Page 7for internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive: Half-bridge DriveIn half-bridge IGBT drive, opto-couplers offer two functions(1)safety isolation &(2) shifting the potential of the gatesignal from uc potential to high-side potentialIf safety isolation between IGBT& micro-controller is notneeded, then"Level Shift" can replace opto-coupling andrealize function(2)OptoHigh-sideHigh-sidecouplerDriverIGBTMicro-Opto-LoW-sideLow-sidecontrollercouplerDriverIGBTZH Liang - Al AP05Dec2003Page 8for internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive Level shiftI FeaturesHVc(600V/1200V)沿PULSERFILTERShort Signal DelayPULSE■Cost- effectiveGEN■ No Safety Isolationevel Shift Half-bridge DriverI BenefitHigh-side““°IGBTO Saving Opto-couplersLevel(lower system costShiftMicro● Wider range ofcontrollerLevelLow-side■■■■■直■口m留■Switching FrequencyShiftIGBT(higher flexibility)ZH Liang - Al AP05Dec2003Page 9for internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive: CLTNEWO CLT-Coreless Transformer (for signal transmissionu Coils(Primary Secondary Side)realized on SiliconO Short Signal Delay (allowing high or low switching frequencyu Lower Cost(compared to 1200V level-shift driver日 Safety IsolationCLT Half-bridge DriverHigh-sideCLT Single DriverIGBTCLTMicro-controllerCLTIGBTMicro-controllerLoW-sideIGBTZH Liang - Al AP05Dec2003agefor internal use onlyInfineon Technologies Asia PacificInfineontechnologiesIGBT Gate Drive: Boot-strapBoot-strap circuit includes only a diode and a capacitora In half-bridge drive, the boot-strap circuit can replace the high-sidepower supply and make single-supply operation possibleWhen the low-side IGBT (or FWD)is on, the diode is forwardbiased and the capacitor is charged by the low-side power supplyvia the low-side IGBT and stores the energyWhen the low-side IGBt(and FWD)is OFF, the diode is reversebiased and blocks the dc-bus voltage to protect the low-sidecircuit.
