Douglas Bailey on automotive power systems
From Interview with Doug Bailey, Vice President Marketing & Applications Engineering, Power Integrations · · Power Electronics News
“The right thing to do is to get rid of the 12 volt lead acid battery and replace it with little power supplies so you can provide energy to all the small applications like lighting systems, seat heaters, navigation systems, and electrical systems with power converters.”

About Douglas Bailey
In a September 2023 interview at PCIM, Doug Bailey, Vice President of Marketing and Applications Engineering at Power Integrations, discussed the company's recent product launches and its focus on gallium nitride (GaN) technology. He stated that the company introduced a new module driver for IGBT and silicon carbide modules, highlighting its data telemetry feature for temperature monitoring in high-voltage modules. Bailey also mentioned products such as a power factor corrector with integrated GaN and a "Mini cap" product for small adapters. He described Power Integrations' approach to GaN, saying the company's rule is that "if GaN can do something, it should do it because it's better and cheaper than any other way of doing it," and noted the launch of an automotive-qualified 900-volt GaN device for replacing 12-volt systems in vehicles. Bailey discussed the company's commitment to GaN on Sapphire technology, stating it provides a "more homogeneous film with fewer dislocations and inclusions" compared to GaN on silicon. He expressed confidence in reaching 1200-volt GaN devices for 800-volt systems in the future. Regarding vertical GaN technology, Bailey said he believes in it but described it as "still a little bit science project world at the moment because of the costs involved," adding that "eventually the industry will get there."
