Dispelling a Myth – GaN and Motor Drivers
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.
