GaN Is Revolutionizing Motor Drive Applications

GaN Is Revolutionizing Motor Drive Applications

In last month’s Safety & Compliance column in How2Power, “WBG Semiconductors Pose Safety And EMI Challenges In Motor Drive Applications,”[1]Kevin Parmenter made some assertions about the difficulties of using SiC, and to a lesser extent GaN, power semiconductors in large motor-drive applications. This commentary is a response to that article, showing that GaN can be a game changer in low-voltage integrated motors.

Podcast - Spirit Behind the Screen: EPC's Alex Lidow and GaN Reliability

Podcast - Spirit Behind the Screen: EPC's Alex Lidow and GaN Reliability

In this episode, Alex Lidow and Marti McCurdy discusses EPC’s test-to-failure method in improving gallium nitride (GaN) devices. According to Alex, testing to failure has allowed EPC to tease out the exact stressors that cause failure and improve EPC’s GaN devices 10-100 times the reliability of commercial devices, and even 100 times reliability in space applications.

Alex and Marti discuss:

(1:30) Why test to fail
(4:14) Learning from failure data and stressors
(11:38) Safe Operating Area
(14:30) Mechanical stressors
(17:45) EPC Space

Thermal Management of Chip-Scale GaN Devices

Thermal Management of Chip-Scale GaN Devices

This article discusses the challenges that thermal management raises due to increase power density, especially with chip-scale packaging (CSP). What is sometimes overlooked, however, is that CSP eGaN® power FETs and integrated circuits have excellent thermal performance when mounted on standard printed circuit board (PCBs) with simple methods for attaching heat sinks. Simulations, supported by experimental verification, examine the effect of various parameters and heat flow paths to provide guidance on designing for performance versus cost.

The 48 V Revolution: Why GaN Plus Digital Control for Ultra-thin Laptops

The 48 V Revolution: Why GaN Plus Digital Control for Ultra-thin Laptops

This article discusses how GaN-based solutions coupled with digital control increase efficiency, shrink the size, and reduce system costs for high density computing applications like ultra-thin laptops and high-end gaming systems. As computers, displays, smartphones and other consumer electronics systems become thinner and more powerful over the past decade, there is increasing demand for addressing the challenge of thinner solutions while extracting more power out of limited space. To address this challenge, the comparative advantages of various non-isolated DC-DC step-down topologies for ultra-thin 48 V – 20 V power solutions that are designed to fit inside a notebook computer or an ultra-thin display are examined.

Layout Considerations for GaN Transistor Circuits

Layout Considerations for GaN Transistor Circuits

Gallium nitride (GaN) transistors have been in mass production for over 10 years. In their first few years of availability, the fast switching speed of the new devices – up to 10 times faster than the venerable Si MOSFET – was the main reason for designers to use GaN FETs. As the pricing of GaN devices normalized with the MOSFET, coupled with the expansion of a broad range of devices with different voltage ratings and power handling capabilities, much wider acceptance was realized in mainstream applications such as DC-DC converters for computers, motor drives for robots, and e-mobility bikes and scooters. The experience gained from the early adopters has led the way for later entrants into the GaN world get into production faster. This article is the first in a series of articles discussing three topics that can help power systems designers achieve the most out of their GaN-based designs at the lowest cost. The three topics are: (1) layout considerations; (2) thermal design for maximum power handling; and, (3) EMI reduction techniques for lowest cost.

Intrinsic Failure Mechanisms in GaN-on-Si Power Transistors

Intrinsic Failure Mechanisms in GaN-on-Si Power Transistors

Standard qualification testing for semiconductors typically involves stressing devices at-or-near the limits specified in their data sheets for a prolonged period of time, or for a certain number of cycles. The goal of qualification testing is to have zero failures out of a large group of parts tested. By testing parts to the point of failure, an understanding of the amount of margin between the data sheet limits can be developed, but more importantly, an understanding of the intrinsic failure mechanisms of the semiconductor can be found.

Efficient Power Conversion (EPC) and BrightLoop Converters Combine Design Expertise to Produce Smaller, Lighter Converters for Performance eMotorsport Vehicles

Efficient Power Conversion (EPC) and BrightLoop Converters Combine Design Expertise to Produce Smaller, Lighter Converters for Performance eMotorsport Vehicles

EL SEGUNDO, Calif. — December 2020 — BrightLoop Converters has greatly reduced the size, cost and improved reliability of its latest BB SP DC-DC buck converters thanks to Efficient Power Conversion Corporation’s (EPC) EPC2029 enhancement-mode gallium nitride (eGaN®) FET transistors. By switching from silicon (Si) transistors to gallium nitride (GaN), BrightLoop was able to increase the switching frequency of their design from 200 kHz to 600 kHz, while keeping the same efficiency. This design change increased the power density of the solution by a factor of approximately two and this resulted in lower cost by enabling the implementation of a smaller enclosure.

EPC’s EPC2029 is an 80 V, 48 A eGaN® FET featuring a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint.
