Power Integrations Unveils MotorXpert v3.0 for FOC Control

Power Integrations Introduces MotorXpert v3.0 for Enhanced Motor Control

Power Integrations (NASDAQ: POWI), a leading name in high-voltage integrated circuits for energy-efficient power conversion, has unveiled the latest version of its advanced software suite, MotorXpert v3.0. This innovative tool is designed specifically for configuring, controlling, and sensing Brushless Direct Current (BLDC) inverters, utilizing the company’s state-of-the-art BridgeSwitch motor-driver integrated circuits. With this new release, Power Integrations embraces shuntless and sensorless technology for field-oriented control (FOC), streamlining the processes involved in motor management.

Additions and Improvements in MotorXpert v3.0

MotorXpert v3.0 includes remarkable advancements that enhance user interactions. Cristian Ionescu-Catrina, a product marketing manager at Power Integrations, expressed, "MotorXpert simplifies the process of designing sensorless motor drives. This version introduces a two-phase modulation scheme, particularly advantageous for applications exposed to high-temperature settings, such as in hot-water circulation pumps." This new modulation significantly reduces inverter switching losses by an impressive 33 percent.

Key Features of the Software Suite

The latest iteration of MotorXpert encompasses three crucial components that streamline the development process:

1. The incorporation of sophisticated mathematical algorithms on the local microcontroller unit (MCU) or digital signal processor (DSP) promptly generates accurate feedback signals from the BridgeSwitch IC, ensuring precise control over the switching patterns.
2. A host-side application cleverly interprets inverter actions, serving vital data in an actionable format suitable for engineering analysis.
3. The user-friendly control interface empowers development engineers to experiment freely, facilitating a smoother transition to final product design.

Technological Compatibility and Implementation

This suite is notable for its MCU-agnostic nature and comes with a detailed porting guide aimed at simplifying deployment across various MCUs, adhering to common C language and MISRA standards.

Enhanced User Experience and Functionality

The user interface of MotorXpert v3.0 boasts a graphical visualization tool akin to a digital oscilloscope, streamlining the process of designing and configuring operational parameters while simplifying debugging tasks. Developers will appreciate parameter tooltips that include a tuning assistant, significantly improving the development experience. The new version supports both Voltage/Frequency (V/F) and Current/Frequency (I/F) controls, allowing motor startups under any load conditions. The selectable two-phase modulation scheme enables developers to balance inverter temperature against torque ripple, particularly beneficial for applications like hot water circulation pumps, ultimately lowering heatsinking and enclosure costs.

Power Integrations' BridgeSwitch IC and Its Applications

At the heart of the MotorXpert suite is the BridgeSwitch IC, a half-bridge motor driver that incorporates low RDSON FREDFET switches alongside controllers and drivers housed in a thermally efficient design. This system incorporates sensorless feedback, fault reporting, and vital self-protection features, suitable for applications ranging from 30 W to 1 HP (750 W).

Potential applications for this innovative technology include fans for air conditioning systems, refrigerator compressors, fluid pumps, and even washing machine and dryer drums. Additionally, it can effectively be utilized in industrial fans, heat pumps, and range hoods.

Accessibility and Resources for MotorXpert v3.0

MotorXpert v3.0 is freely available under an end-user license agreement. This software suite includes comprehensive resources such as a quick start guide, a software manual, a porting guide for MCUs, and libraries for single- and three-phase systems, along with a video tutorial to further aid developers.
