Power electronics technologies have undergone a radical transformation following the introduction of wide-bandgap (WBG) devices, such as silicon carbide (SiC) and gallium nitride (GaN). These materials, in fact, have characteristics that make them particularly suitable for applications that operate at high voltages and high switching frequencies. To fully exploit the potential offered by wide-bandgap semiconductors, designers must understand the challenges of these materials.
Power electronics design will continue to focus on reducing the size and complexity of devices while increasing their functionality. The design will increasingly incorporate AI and machine learning algorithms to improve performance, monitor system health, and optimize energy management. Future developments will be integrated not only in automotive, industrial, aerospace markets, but also with IoT technologies to create a more connected and automated energy system.
Semiconductor devices are used to drive motors and control power. As efficiency standards for these applications get better, cost-effective and energy-efficient control solutions, test and measurement solutions, and transducers/sensors make design easier and offer a high level of integration, as well as better safety features and certified isolation capabilities.
Moreover, using energy harvesting techniques and new power semiconductors to make electrical and electronic systems work as well as possible is an important part of engineering.
The PowerUP Expo is a three-day virtual conference and exhibition focusing on power electronics. With an exhibition area, live stage, and messaging center, the PowerUP Expo functions similarly to a live exhibition and conference. This technical conference will include a number of sessions including keynotes, panel discussions, technical presentations, and tutorials on a variety of subject matters, including significant technical trends, market demands, and new application areas. The exhibition area will include virtual booths from top power electronics businesses and a Live Chat facility that allows attendees to communicate with booth staff directly.
PowerUP offers an opportunity for engineers, managers, academics, and students from all over the world to learn the latest technological advances and applications in Power Electronics and to connect with each other in our community. The newest trends and advancements in the field of power electronics, from components to intelligent systems, are discussed by leaders in the industry.
Conference Tracks:
- June 27: Tutorial/Lectures, Panel Discussion & Conference Preview
- June 28: Wide Bandgap Semiconductors and Power Applications
- June 29: Power Conversion and Management Design Trends in low and high power
Detailed agenda can be found at PowerUP Expo.

While the adoption of GaN devices has expanded in recent years due to their superior high-speed switching characteristics, the speed of Control ICs, which are responsible for directing the driving of these devices, has become challenging.
In response, ROHM has further evolved its ultra-high-speed pulse control technology Nano Pulse Control™. It is cultivated for power supply ICs, succeeding in significantly improving the control pulse width from the conventional 9ns to an industry-best 2ns. Leveraging this technology allowed ROHM to establish its ultra-high-speed Control IC technology that maximizes the performance of GaN devices.
When pursuing miniaturization of the power supply circuit, it is necessary to reduce the size of the peripheral components through high-speed switching. Achieving this requires a Control IC that can take advantage of the drive performance of high-speed switching devices such as GaN devices.
To propose solutions that include peripheral components, ROHM established ultra-high-speed Control IC technology optimized for GaN devices utilizing proprietary analog power supply technology Nano Pulse Control™.
ROHM is currently working to commercialize Control ICs utilizing this technology, with plans to start sample shipment of 100V 1ch DC-DC Control IC in the second half of 2023. Using in conjunction with ROHM GaN devices (EcoGaN™ series) is expected to result in significant energy savings and miniaturization in a variety of applications, including base stations, data centers, FA (Factory Automation) equipment, and drones.
Going forward, ROHM will continue to develop products that solve social issues by pursuing greater ease-of-use in applications centered on its strengths in analog technology.
