Description

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. Modularity and symmetrical structure in DAB allow for stacking converters to achieve high power throughput and facilitate a bidirectional mode of operation to support battery charging and discharging applications.

This 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.

This design can be run on a C2000™ TMS320F280039C real-time MCU.

Release Notes

Shown below lists all the software revision history for this reference design:

Software Version	SDK Release	Changelog
v1.00.00	3.03.00.00	First release, on F28004x devices in C2000Ware Digital Power SDK
v1.01.00	4.00.00.00	Bug fixes & Enhancements: Change compiler version (from v20.2.1 to v21.6.0) Add source-lookup path for driverlib
v1.02.00	4.03.00.00	Changes & Enhancements: Software updates to device.c, device.h, driverlib.h to account for changes in C2000Ware Projectspec updates to account for changes to Kit.json output from sysconfig tool Changed compiler version (from v21.6.0.LTS to v22.6.0.LTS)
v2.00.00	5.00.01.00	New device support & Enhancements: Added F28003x as a supported device Added support for extended-phase shift
v3.00.00	5.02.00.00	Updated device support & Enhancements: Updated software to support new HW Revision TIDA-010054E4 Additional protection with smart gate drivers Secondary side sensing with isolated delta-sigma modulators instead of isolated amplifiers. ADC interface on C2000 replaced with the SDFM peripheral. Relays to disconnect secondary side output. Closed loop voltage and closed loop current control mode for reverse direction power flow. Deprecated support for F28004x, only F28003x device will be supported
v3.01.00	5.03.00.00	Bug fixes: Fixed an PWM issue, which could lead to skip one PWM cycle for phase shifts greater than 0.5. This led to an unexpected rise in current, which tripped the system.
