QY70 MITSUBISHI

QY70 MITSUBISHI Power Board

Product  Description：

A Mitsubishi Power Board typically consists of high-performance power semiconductors (like IGBTs or MOSFETs) mounted on a specialized PCB or substrate. These boards often incorporate gate drive circuitry, protection logic, and thermal management components. They are designed to interface directly with a microcontroller (MCU) or Digital Signal Processor (DSP) to convert DC power into variable frequency AC power or vice versa.

Product Parameters

While specific parameters vary by model (e.g., the DIP-IPM series vs. Large DIPIPM), common specifications include:

• Voltage Rating: Typically ranges from 600V to 1200V for industrial applications, with specialized versions reaching 1700V or higher.

• Current Rating: Ranges from 5A for small household appliances to over 1000A for heavy industrial drives.

• Isolation Voltage: Usually rated at 1500Vrms or 2500Vrms to ensure safety between high-voltage and low-voltage circuits.

• Switching Frequency: Optimized for ranges between 5kHz and 20kHz, balancing efficiency and noise.

• Operating Temperature: Generally rated for junction temperatures up to 150 degrees Celsius.

Product Advantages

Mitsubishi Power Boards are renowned for several key technological benefits:

• High Reliability: Built with advanced CSTBT (Carrier Stored Trench-Gate Bipolar Transistor) technology, which reduces power loss and improves durability.

• Integrated Protection: Most boards include built-in protection against short-circuits, over-temperature, and under-voltage lockout (UVLO).

• Compact Footprint: By integrating the gate drive and power stage, these boards significantly reduce the physical size of the final inverter system.

• Energy Efficiency: Low collector-emitter saturation voltage and minimized switching losses contribute to high system-level efficiency.

Important Precautions

To ensure longevity and safety, users should adhere to the following guidelines:

• Thermal Management: Adequate heat sinking and thermal grease application are mandatory. Overheating is the primary cause of semiconductor failure.

• Static Discharge: These boards are sensitive to Electrostatic Discharge (ESD). Handle them only in ESD-protected environments.

• Voltage Spikes: Ensure proper snubber circuits or decoupling capacitors are used to prevent transient voltage spikes from exceeding the maximum ratings.

• Mounting Torque: When attaching the board to a heat sink, follow the specified screw torque settings to avoid cracking the ceramic substrate.

Product Applications

Mitsubishi Power Boards are versatile and found in numerous sectors:

• Industrial Automation: Used in AC motor drives, servo amplifiers, and CNC machinery.

• Renewable Energy: Central to solar inverters and wind turbine converters.

• Consumer Electronics: Powering inverter air conditioners, washing machines, and refrigerators.

• Automotive: Found in the drive inverters of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV).

• Power Supplies: Used in Uninterruptible Power Supplies (UPS) and medical imaging equipment.
