QX42 MITSUBISHI Power Board

Product  Description：

Mitsubishi Power Modules serve as the core switching elements in power electronic systems. They are engineered to handle high voltages and large currents while maintaining minimal energy loss. The lineup includes the DIPIPM series, which integrates power chips, drive circuits, and protection functions into a single compact transfer-molded package, and the larger industrial IGBT modules used in heavy machinery.

Advanced technologies like the Carrier Stored Trench-Gate Bipolar Transistor (CSTBT) are employed to reduce collector-emitter saturation voltage, thereby improving overall system efficiency. Additionally, Mitsubishi's SiC modules offer significantly lower switching losses and higher thermal conductivity compared to traditional silicon-based devices, allowing for much smaller and lighter end products.

Product Parameters

The performance of these modules is defined by several critical electrical and thermal specifications. Standard parameters typically found in Mitsubishi product data sheets include:

• Rated Collector-Emitter Voltage ($V_{CES}$): This is the maximum voltage the device can withstand when in the off-state, typically ranging from 600V to 6500V depending on the series.

• Rated Collector Current ($I_C$): The continuous current the module can handle, with common values ranging from 5A for small appliances to over 1000A for industrial traction.

• Collector-Emitter Saturation Voltage ($V_{CE(sat)}$): A measure of conduction loss; lower values indicate higher efficiency.

• Isolation Voltage ($V_{iso}$): The dielectric strength between the internal circuitry and the base plate, often rated at 2500Vrms or higher for safety.

• Junction Temperature ($T_j$): The operating temperature limit of the semiconductor chips, typically reaching up to 150°C or 175°C in high-performance models.

• Power Dissipation ($P_d$): The maximum amount of heat energy the module can safely dissipate during operation.

Product Advantages

Mitsubishi Power Boards are recognized globally for their reliability and performance. Key benefits include:

• High Efficiency: By utilizing proprietary chip structures like CSTBT and SiC-MOSFETs, these modules minimize both conduction and switching losses, leading to lower energy consumption and reduced heat generation.

• Integration and Compactness: Intelligent Power Modules (IPMs) include built-in gate drive circuitry and protection logic (for over-current, short-circuit, and under-voltage), which reduces the number of external components and simplifies the overall PCB design.

• Thermal Management: The use of high-thermal-conductivity insulation sheets and optimized baseplate designs ensures efficient heat transfer from the chips to the external heatsink.

• High Reliability: Extensive testing and robust packaging allow these modules to operate in harsh environments, including those with high vibration and extreme temperature cycles.

Precautions

To ensure long-term performance and safety, certain guidelines must be followed during handling and installation:

• Electrostatic Discharge (ESD): Power modules are sensitive to static electricity. Technicians should use grounded wrist straps and anti-static mats when handling the devices to avoid damaging the internal gate structures.

• Thermal Interface Material (TIM): A uniform layer of thermal grease or a high-quality thermal pad must be applied between the module baseplate and the heatsink to prevent localized overheating.

• Mounting Torque: When securing the module to a heatsink or connecting terminals, it is vital to follow the specified torque limits. Excessive torque can crack the resin case, while insufficient torque leads to poor thermal contact or electrical resistance.

• Electrical Safety: Always ensure that all power sources are disconnected and capacitors are fully discharged before mounting or performing maintenance. High-voltage terminals can remain lethal for several minutes after power is shut off.

• Polarity and Wiring: Incorrect polarity on the DC-link terminals or gate-drive signals can lead to immediate and catastrophic failure of the module.

Product Applications

These power boards and modules are essential components in a wide variety of modern technological sectors:

• Home Appliances: Used in air conditioners, refrigerators, and washing machines to drive motors with variable frequency, significantly reducing household energy use.

• Industrial Automation: Powering AC servos, industrial robots, and general-purpose inverters for factory equipment and conveyor systems.

• Renewable Energy: Converting DC power from solar panels and wind turbines into grid-synchronized AC power.

• Automotive: Serving as the main inverter module in electric vehicles (EV) and hybrid electric vehicles (HEV) to control traction motors.

• Railway Traction: Heavy-duty modules are used in high-speed trains and subways for propulsion and auxiliary power supply systems.

• Power Infrastructure: Utilized in Uninterruptible Power Supplies (UPS) and High Voltage Direct Current (HVDC) transmission systems.
