马达控制电源板STEVAL-IPMNG3Q

The STEVAL-IPMNG3Q is a compact motor drive power board based on SLLIMM-nano™ (small low-loss intelligent molded module) 2nd series (STGIPQ3H60T-HZ). It provides an affordable and easy-to-use solution for driving high power motors for a wide range of applications such as power white goods, air conditioning, compressors, power fans, high-end power tools and 3-phase inverters for motor drives in general. The IPM itself consists of short-circuit rugged IGBTs and a wide range of features like undervoltage lockout, smart shutdown, embedded temperature sensor and NTC, and overcurrent protection.

The main characteristics of this evaluation board are small size, minimal BOM and high efficiency. It consists of an interface circuit (BUS and VCC connectors), bootstrap capacitors, snubber capacitor, hardware short-circuit protection, fault event and temperature monitoring. In order to increase the flexibility, it is designed to work in single- or three-shunt configuration and with triple current sensing options: three dedicated onboard op-amps, an internal IPM op-amp and op-amps embedded in the MCU. The Hall/Encoder section completes the circuit.

With these advanced characteristics, the system is designed to achieve fast and accurate current feedback conditioning, satisfying the typical requirements for field-oriented control (FOC). The STEVAL-IPMNG3Q is compatible with ST ’s STM32-based control board, enabling designers to build a complete platform for motor control.

 Input voltage: 125 - 400 VDC

 Nominal power: up to 300 W

 Input auxiliary voltage: up to 20 V DC

 Motor control connector (32 pins) interfacing with ST MCU boards

 Single- or three-shunt resistors for current sensing (with sensing network)

 Three options for current sensing: external dedicated op-amps, internal SLLIMM-nano op-amp (single) or through MCU

 Overcurrent hardware protection

 IPM temperature monitoring and protection

 Hall sensors (3.3 / 5 V)/encoder inputs (3.3 / 5 V)

 IGBT intelligent power module:

IPM模块

IPM(Intelligent Power Module)，即智能功率模块，不仅把功率开关器件和驱动电路集成在一起。而且还内部集成有过电压，过电流和过热等故障检测电路，并可将检测信号送到CPU。它由高速低功耗的管芯和优化的门极驱动电路以及快速保护电路构成。即使发生负载事故或使用不当，也可以保证IPM自身不受损坏。

特 点

IPM与以往IGBT模块及驱动电路的组件相比具有如下特点：

(1)内含驱动电路。设定了最佳的IGBT驱动条件，驱动电路与IGBT间的距离很短，输出阻抗很低，因此，不需要加反向偏压。所需电源为下桥臂1组，上桥臂3组，共4组。

(2)内含过电流保护(OC)、短路保护(SC)。由于是通过检测各IGBT集电极电流实现保护的，故不管哪个IGBT发生异常，都能保护，特别是下桥臂短路和对地短路的保护。

(3)内含驱动电源欠电压保护(UV)。每个驱动电路都具有UV保护功能。当驱动电源电压UCC小于规定值UV时，产生欠电压保护。

(4)内含过热保护(OH)。OH是防止IGBT、FRD(快恢复二极管)过热的保护功能。IPM内部的绝缘基板上没有温度检测元件来检测绝缘基板温度Tcoh(IGBT、FRD芯片异常发热后的保护动作时间比较慢)。R—IPM进一步在各IGBT芯片内设有温度检测元件，对于芯片的异常发热能高速实现OH保护。

(5)内含报警输出(ALM)。ALM是向外部输出故障报警的一种功能，当OH及下桥臂OC、Tjoh、UV保护动作时，通过向控制IPM的微机输出异常信号，能切实停止系统。

(6)内含制动电路。和逆变桥一样，内含IGBT、FRD、驱动，通过外接制动电阻可以方便的实现能耗制动。
