Insights
This software release represents a significant technological advancement in motor control systems, with substantial commercial implications. The elimination of shunts and sensors through software intelligence directly translates to reduced bill of materials (BOM) costs for manufacturers - a critical advantage in the highly competitive motor control market.
The 33% reduction in inverter switching losses is particularly noteworthy for two reasons: First, it enables manufacturers to reduce heatsink requirements and enclosure costs, potentially saving several dollars per unit in high-volume applications. Second, it positions Power Integrations favorably in the growing heat pump market, which is experiencing rapid growth due to global electrification initiatives.
The market opportunity is substantial, spanning multiple sectors:
- Home appliances (refrigerators, washers, dryers)
- HVAC systems and heat pumps
- Industrial fans and pumps
- Electric vehicle charging infrastructure
The software's MCU-agnostic approach and MISRA compliance are strategically important, as they lower barriers to adoption and accelerate time-to-market for customers. This could help Power Integrations capture a larger share of the motor driver IC market, estimated to reach
Notably, the free availability of MotorXpert software creates a compelling business model - while the software is provided at no cost, it drives sales of Power Integrations' high-margin BridgeSwitch ICs. This approach has proven successful in the semiconductor industry, as it creates customer lock-in and recurring revenue streams.

Cristian Ionescu-Catrina, product marketing manager at Power Integrations said: “MotorXpert simplifies single- and three-phase sensorless motor-drive designs. In this version 3.0 release, we have added a two-phase modulation scheme, which is ideal for applications that work in high temperature environments such as hot-water circulation pumps. The new modulation reduces inverter switching losses by 33 percent. Version 3.0 also features a five-fold improvement to our waveform visualization tool and an enhanced zoom function, giving developers substantially more information for motor tuning and debugging.”
MotorXpert 3.0 comprises three main sections:
- Sophisticated mathematical algorithms resident on the local MCU or DSP construct accurate feedback signals from the BridgeSwitch IC and provide real-time control of the switching patterns.
- A host-side application interprets inverter actions and displays critical data in actionable format for engineering analysis.
- The easy-to-use control interface permits development engineers to experiment and quickly converge to a final product.
MotorXpert suite is MCU-agnostic and includes a comprehensive porting guide to simplify deployment with a wide range of MCUs. It is implemented in common C language to MISRA standards.
The MotorXpert v3.0 host-side application includes a graphical user interface with Power Integrations’ digital oscilloscope visualization tool that makes it easy to design and configure parameters and operation and simplifies debugging. Parameter tool tips and a tuning assistant improve the development process, and the intuitive parameter list provides easy motor tuning. The new version also features both V/F and I/F control, which permits motor startup in any load condition. A selectable two-phase modulation scheme allows developers to trade off temperature of the inverter vs torque ripple which is beneficial in applications such as hot water circulation pumps, reducing heatsinking requirements and enclosure cost. Development time is greatly reduced by the included single- and three-phase code libraries with sensorless support, reference designs, and other tools such as a power supply design and analysis tool.
The BridgeSwitch IC is a half-bridge motor driver of low RDSON FREDFET switches, controllers and drivers in a thermally efficient package. Sensorless feedback, fault reporting, and self and load protection are also available for applications from 30 W to 1 HP (750 W).
Applications include indoor and outdoor air conditioning fans, refrigerator compressors, fluid pumps, washing machine and dryer drums, range hoods, industrial fans and heat pumps.
