Mitsubishi PM20CHA060-1 | Integrated CIB Module for Compact Motor Drives
The Mitsubishi PM20CHA060-1 is a highly integrated power module designed to simplify and streamline the development of low-power motor control and power conversion systems. As a Converter-Inverter-Brake (CIB) module, it consolidates the three essential stages of a variable frequency drive into a single, compact package. This intelligent integration makes it a go-to solution for engineers looking to reduce system size, shorten design cycles, and enhance the reliability of their industrial automation applications.
Unpacking the "All-in-One" Advantage: The CIB Architecture
At the heart of the Mitsubishi PM20CHA060-1's value is its CIB topology. Instead of sourcing, qualifying, and assembling separate components, this module provides a thermally and electrically optimized subsystem. For system designers, this translates directly into tangible benefits.
- Converter Stage: Features a three-phase diode bridge rectifier to efficiently convert incoming AC power into a stable DC bus voltage. This eliminates the need for an external rectifier, saving valuable PCB real estate and reducing assembly complexity.
- Inverter Stage: A robust three-phase bridge built with six 600V/20A IGBTs forms the core of the motor drive. These components are carefully matched within the module for balanced switching characteristics, minimizing harmonics and ensuring smooth motor operation.
- Brake Chopper: An integrated IGBT and freewheeling diode create a brake circuit. This is critical for managing regenerative energy during motor deceleration, preventing DC bus overvoltage and allowing for rapid, controlled stopping in dynamic applications like servo drives.
Solving Real-World Challenges with the PM20CHA060-1
The true measure of a component is how it performs in the field. The Mitsubishi PM20CHA060-1 excels by addressing specific pain points across various industrial sectors:
- General-Purpose Inverters & Small Conveyors: In space-constrained control cabinets, the module's high level of integration is a significant advantage. It allows for a smaller overall drive footprint and simplifies thermal management by consolidating major heat sources into one well-defined area, making heatsink design more effective.
- Servo Drives & Machine Tool Control: The built-in brake chopper is indispensable for applications requiring precise positioning and fast dynamic response. It provides a reliable, integrated solution for dissipating braking energy, enhancing system safety and performance without the complexity of an external braking unit.
- Compact Uninterruptible Power Supply (UPS) Systems: Reliability is paramount in UPS applications. By using a single, factory-tested module like the PM20CHA060-1, you reduce the number of interconnects and potential points of failure compared to a discrete solution, leading to a more robust and dependable power conversion stage.

Is the PM20CHA060-1 the Right Fit for Your Design?
Choosing the right power module is crucial for project success. The PM20CHA060-1 is an ideal choice for new designs or retrofits of low-power systems (typically under 2.2 kW) where development speed, reliability, and compactness are key drivers. While a fully discrete component solution might offer more layout flexibility, it comes at the cost of increased design and validation time. Compared to more advanced Intelligent Power Modules (IPMs), the PM20CHA060-1 offers a cost-effective solution for applications that do not require integrated gate drivers and extensive built-in protection features. It provides the core power stage, giving designers the freedom to implement their own custom control and protection schemes.
For designers focused on building dependable, cost-efficient, and compact power conversion systems, the integrated CIB architecture of the Mitsubishi PM20CHA060-1 offers a clear path to success.
