Technical FAQs 4

What is the future of bidirectional power supplies?

Looking ahead, the evolution of bidirectional power supplies is poised to continue, driven by demands for higher efficiency, increased power density, and enhanced integration capabilities with smart grids and IoT devices.

What is a bidirectional power supply?

A bidirectional power supply demands a different design approach compared to an equivalent unidirectional supply. A unidirectional AC/DC power supply designed for high efficiency uses wide bandgap (WBG) SiC or GaN power devices with a totem-pole power factor correction (PFC) front end driving a DC/DC topology such as an LLC resonant converter.

How do you design a bidirectional power supply?

Designing a bidirectional power supply starts with determining the voltage and current ratings required by the application. This involves understanding the maximum power transfer requirements between the source and the load, ensuring the bidirectional converter can handle both charging and discharging cycles effectively. 2. Control Strategy

How does a grid-scale energy storage system work?

Figure 2 shows the main functional blocks in a grid-scale ESS that uses batteries to store energy. Bidirectional power supplies transfer AC power from the grid to the storage system and vice versa.
