Reference Designs and Associated Training Videos

TIDA-01606 10-kW, bidirectional three-phase three-level (T-type) inverter and PFC reference design
This reference design provides an overview on how to implement a bidirectional three-level, three-phase, SiC-based active front end (AFE) inverter and PFC stage. The design uses a switching frequency of 50 kHz and a LCL output filter to reduce the size of the magnetics. A peak efficiency of 99% is achieved. The design shows how to implement a complete three phase AFE control in the DQ domain. The control and software is validated on the actual hardware and on hardware in the loop (HIL) setup.

TIDA-010210 11-kW, bidirectional, three-phase ANPC based on GaN reference design
This reference design provides a design template for implementing a three-level, three-phase, gallium nitride (GaN) based ANPC inverter power stage. The use of fast switching power devices makes it possible to switch at a higher frequency of 100 kHz, reducing the size of magnetics for the filter and increasing the power density of the power stage. The multilevel topology allows the use of 600-V rated power devices at higher DC bus voltages of up to 1000 V. The lower switching voltage stress reduces switching losses, resulting in a peak efficiency of 98.5%

TIDA-010054 Bi-directional, dual active bridge reference design for level 3 electric vehicle charging stations
This reference design provides an overview on the implementation of a single-phase Dual Active Bridge (DAB) DC/DC converter. DAB topology offers advantages like soft-switching commutations, a decreased number of devices and high efficiency. The design is beneficial where power density, cost, weight, galvanic isolation, high-voltage conversion ratio, and reliability are critical factors, making it ideal for EV charging stations and energy storage applications. Modularity and symmetrical structure in the DAB allow for stacking converters to achieve high power throughput and facilitate a bidirectional mode of operation to support battery charging and discharging applications.
