Presentation: Dual-Phase AC-DC Transformer for Battery Charging Purposes
The upcoming September Virtual Conference on EV Engineering, scheduled from the 15th to the 18th of 2025, will feature a webinar presented by Synopsys, showcasing a unique battery charging design. This design, created using SaberEXP, a piecewise linear circuit simulation tool from Synopsys, offers a virtual battery charging solution that demonstrates exceptional flexibility in designing and optimizing both hardware and software.
The conference, which is free to register, encompasses the entire EV engineering supply chain and ecosystem, covering topics such as motor and power electronics design and manufacturing, cell development, battery systems, testing, powertrains, thermal management, circuit protection, wire and cable, EMI/EMC, and more.
The Design
The design under discussion is a two-stage AC-DC converter system, consisting of a front-end AC-DC two phase interleaved boost converter and a CLLC DC-DC full bridge resonant converter. The front-end converter delivers a constant voltage (600V DC) at the intermediate DC bus, while the second stage of the converter facilitates efficient and precise control of power delivered to the battery.
The outputs of the design can provide either constant current or constant voltage, ranging from 250V DC to 400V DC and charging current up to 15A. The design also undergoes time-domain simulations under both normal and fault conditions to ensure its reliability and safety.
The Benefits of Simulation in Design
The use of simulation tools like Saber offers numerous benefits in the design cycle. Rapid prototyping allows for the testing of different design iterations, reducing the need for physical prototypes and speeding up the development process. Error reduction is another significant advantage, as potential issues can be identified early, avoiding costly rework and reducing overall design cycle time.
Simulation tools also help optimize the performance of the converter, ensuring it operates efficiently and reliably under various conditions. By simulating failure scenarios and stress tests, designers can ensure that the system meets safety and reliability standards, reducing the risk of malfunctions or hazards.
In the context of AC-DC converter systems, accurate simulation can lead to more efficient converter designs, reducing energy losses and improving overall system efficiency. The flexibility and scalability of simulation tools allow for easy adaptation to changing design requirements or new technologies.
Although the Saber simulation tool suite is not explicitly mentioned in the search results regarding the optimization of a two-stage AC-DC converter system for battery charging design, its general application in optimizing AC-DC converter systems would likely align with these principles.
