Design unveiled for 800V inverter from Texas Instruments

Texas Instruments has developed a reference design for an 800 V, 11 kW three-level, three-phase inverter using gallium nitride (writes Nick Flaherty). The inverter uses a 6.6 kW active neutral-point clamped (ANPC) inverter design with a 600 V LMG3422R030 GaN FET. This enables a switching frequency of 100 kHz to reduce the size of the […]

Dual-component power converter

Premo has developed an 11 kW power converter using its patented technology that integrates multiple magnetic components (writes Nick Flaherty). The 3DP-11KWHVHV combines a full-bridge 150 µH LLC resonant transformer and 25 µH resonant choke in a single unit. This cuts the volume of the converter by up to half, and can reduce the amount of […]
