Vishay Intertechnology, Inc. introduced 16 new 650 V and 1200 V silicon carbide (SiC) Schottky diodes in the industry-standard SOT-227 package. Designed to deliver high speed and efficiency for high frequency applications, the Vishay Semiconductors devices offer the best trade-off between capacitive charge (QC) and forward voltage drop for diodes in their class.
The devices consist of 40 A to 240 A dual diode components in a parallel configuration, and 50 A and 90 A single phase bridge devices. Built on state of the art thin wafer technology, the diodes feature a low forward voltage drop down to 1.36 V that dramatically reduces conduction losses for increased efficiency. Further increasing efficiency, the devices offer better reverse recovery parameters than Si-based diodes and have virtually no recovery tail.
Typical applications for the components will include AC/DC PFC and DC/DC ultra high frequency output rectification in FBPS and LLC converters for photovoltaic systems, charging stations, industrial UPS, and telecom power supplies. In these applications, the diodes’ low QC down to 56 nC allows for high speed switching, while their industry-standard package offers a drop-in replacement for competing solutions.
The diodes deliver high temperature operation to +175 °C and a positive temperature coefficient for easy parallelling. UL-approved to file E78996, the devices feature a large creepage distance between terminals and a simplified mechanical design for rapid assembly.

Power Integrations announced MotorXpert™ v3.0, a software suite for configuration, control and sensing of BLDC inverters that utilize the company’s BridgeSwitch™ motor-driver ICs. The latest release of the software incorporates Power Integrations’ shuntless and sensorless technology for field-oriented control (FOC), adding support for advanced modulation schemes and unconditional startup under any load condition, along with significant improvements to the host user interface and debugging tools.
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.
MotorXpert v3.0 is available at no cost with an end-user license agreement. The software suite comes with a quick start guide, software manual, MCU porting guide, single- and three-phase software libraries and a video tutorial.
