HC-PQ13B MITSUBISHI Power Board

Product  Description：

Mitsubishi Power Boards, often referred to as Power Semiconductor Modules or Intelligent Power Modules (IPM), are high-performance electronic assemblies designed to control and convert electrical power. These boards integrate power switching devices, such as IGBTs (Insulated Gate Bipolar Transistors) or SiC (Silicon Carbide) MOSFETs, with drive circuitry and protection functions to ensure efficient energy management in industrial and consumer applications.

Technical Parameters

The specific parameters of a Mitsubishi Power Board vary depending on the series, such as the DIPIPM or the Large-DIPIPM, but they generally adhere to the following technical specifications:

• Voltage Rating: Typically ranges from 600V for residential appliances to 1200V or 1700V for industrial machinery.

• Current Rating: Capacities usually span from 5A for small fan motors to over 1200A for heavy-duty industrial inverters.

• Switching Frequency: Optimized for frequencies between 5kHz and 20kHz, balancing thermal management with acoustic noise reduction.

• Isolation Voltage: Standard units offer a dielectric breakdown voltage of approximately 1500Vrms to 2500Vrms for safety.

• Junction Temperature: Maximum operating temperatures often reach 150 degrees Celsius, with advanced SiC models pushing these limits further.

Key Advantages

Mitsubishi Electric is a global leader in power electronics, and their power boards offer several distinct benefits:

• High Efficiency: By utilizing advanced trench gate technology and thin-wafer processing, these boards minimize power loss during switching and conduction, leading to lower energy consumption.

• Integrated Protection: Most boards include built-in protection against over-current, short-circuiting, under-voltage, and over-temperature, which simplifies the overall system design and enhances reliability.

• Compact Form Factor: The integration of the gate driver and the power chips into a single package reduces the physical footprint, allowing for smaller and lighter end products.

• Thermal Performance: The use of high-thermal-conductivity materials in the baseplate ensures effective heat dissipation, prolonging the lifespan of the components.

Usage Precautions

To ensure the longevity and safety of the power board, the following precautions must be observed:

• Electrostatic Discharge (ESD): These boards contain sensitive semiconductor gates. Proper grounding and ESD wrist straps must be used during handling to prevent permanent damage.

• Heat Sink Mounting: Thermal grease or a thermal interface material (TIM) must be applied evenly between the board and the heat sink. Excessive or uneven tightening of mounting screws can crack the ceramic substrate.

• Dead Time Settings: When designing the control logic, sufficient "dead time" must be programmed to prevent a "shoot-through" condition, where both the high-side and low-side transistors are on simultaneously.

• Voltage Spikes: Inductive loads can cause voltage surges. External snubber circuits or capacitors are often required to protect the module from exceeding its maximum rated voltage.

Common Applications

Mitsubishi Power Boards are foundational components in modern energy-efficient technology:

• Home Appliances: Used in inverter air conditioners, washing machines, and refrigerators to provide variable speed control for motors.

• Industrial Automation: Employed in AC motor drives, servo amplifiers, and CNC machinery for precise motion control.

• Renewable Energy: Integrated into solar inverters and wind power converters to transform DC energy into grid-compatible AC power.

• Automotive: Utilized in the powertrain inverters of electric vehicles (EVs) and hybrid electric vehicles (HEVs) to manage high-voltage battery discharge.
