EPC’s mission is to make GaN power devices that are higher performance and lower cost compared to silicon. GaN devices increase power density, improve efficiency and enable new applications and with the rising cost of energy globally, it is no surprise that the adoption rate of our GaN devices is accelerating dramatically.

GaN FETs help Solarnative achieve industry-leading power density for solar microinverters, enabling module frame integration to solve the challenges of solar power installation.

EL SEGUNDO, Calif.— November 2022 Solarnative uses GaN devices in its new microinverter to achieve industry-best power density.  The Power Stick is the smallest inverter in the world, with dimensions of 23.9 by 23,2 by 404 millimeters. With an AC output power of 350 W, the volume of 0.19 liters corresponds to a power density of 1.6 kW per liter. By comparison, the IQ 7A microinverter from a market leading supplier delivers 349 watts with a volume of 1.12 liters, corresponding to 0.31 kW per liter – not even one-fifth of the Solarnative device. Despite the extreme size reduction, the European efficiencies are quite comparable, at 96.0 percent for the Power Stick and 96.5 percent for the IQ 7A.

With increasing legislation aimed at higher fuel efficiency standards, vehicle manufacturers are searching for cost-effective solutions to meet these demands while still providing the power required for ever-increasing electronically driven functions.  This article details a bi-directional high power converter for mild-hybrid cars and battery backup units using GaN FETs to achieve efficiency exceeding 96% when converting from 48 V to 14.3 V at 500 kHz switching frequency.

GaN devices have gone from initial R&D to mainstream designs over the last 15 years. Unfortunately, there are many misunderstandings left-over from those early-stage bipolar drive circuit developments or dead-end technology branches. One of the most pernicious is the topic of bipolar drive. In actuality, unipolar drives are the best way to drive eGaN^® FETs.

There is a commonly held belief in the industry that GaN devices are wasted on inverters for electric motors. After all, if the performance of the system is restricted by the use of a 20KHz PWM, then there can be little benefit in using a material that gains the majority of its advantages from faster switching speeds. However, according to Marco Palma, Director of Motor Drives Systems and Applications at EPC, there are some ways that GaN can still prove effective in that role.
