Using GaN power semiconductors solves space constraint challenges typical in electric mobility systems by providing more power in smaller form factors. The DDC48-1K converter is one-third smaller and 50% lighter than standard converters.
With an input voltage range of 24-60VDC and rated at up to 1kW continuous power with an overall efficiency of 97.5% at full load, this converter offers a reliable and efficient solution for electric mopeds and scooters, EV systems and vehicles, and numerous transportation and robotics applications. Power density is 28W/in3 compared to 10W/in3 in converters using other topologies and switches. The high power density results in a significant weight reduction: The design without the case weighs only 345g, and an air-cooled DC/DC of the same power weighs around 750g.
EPowerlabs’ GaN-based DC/DC converter uses GaN Systems 100V E-mode transistors (GS61008P), which leverage high-performance GaNPX embedded packaging and the high current, voltage breakdown, and switching frequency of GaN.
