The core trunk line introduces a 480W gallium nitride power supply scheme, using four gallium nitride devices

2022-06-18

By applying gallium nitride devices to the fast charging charger, the power density of the USB PD fast charging charger is significantly improved, making the charger smaller, supporting more interfaces, getting rid of the traditional impression of big bricks, and making the charger more fashionable. So what changes can Gan bring to traditional power adapters?

The charging head network has obtained a 480W power module launched by the core trunk line, which adopts an efficient pfc+llc power architecture, and the output uses synchronous rectification. Two xg6510b8 gallium nitride switches are used for PFC boost, two xd6506f8 silicon carbide diodes are used for PFC rectification, and two xg6510b8 form a LLC half bridge. The output specification of the power module is 48v10a, and the conversion efficiency reaches 96%, meeting the requirements of high-power Poe applications and USB pd3.1 240W fast charging applications.

The charging head network will analyze this gallium nitride power module to see what changes the introduction of gallium nitride technology has brought to common power modules.

The 480W Gan power density introduced by the core trunk line is about 1.5w/cm ³, It can be seen that the application of the third generation semiconductor power devices significantly reduces the heat dissipation requirements of the power supply and reduces the volume of the power supply. The size of 480W power supply is only equivalent to that of conventional notebook power supply, which meets Poe switch and USB pd3.1 fast charging applications.

In this power supply, the core trunk Gan switch is used in the PFC boost switch and LLC switch. The model is xg6510b8. The PFC boost rectifier adopts xd6506f8 silicon carbide diode. A new generation of semiconductor devices can effectively reduce losses, improve conversion efficiency, and improve the use experience of high-power switching power supply products.
