Design considerations for a 10-kW 3-phase, 3-level bi-directional AC/DC, DC/AC inverter/rectifier

Details

Date: June 28, 2019

This video provides an overview on how to implement a three-level, three-phase, SiC-based AC/DC converter with bi-directional functionality, using our latest reference design. We will cover how a high switching frequency of 50 kHz reduces the size of magnetics for the filter design, resulting in a higher power density. SiC MOSFETs with switching loss enable higher DC bus voltages of up to 800V and lower switching losses with a peak efficiency of >97%. The reference design featured in this video is configurable to work as a two-level or three-level rectifier. For design information on the DC/AC implimentation, see TIDA-01606.
