Applications of Bidirectional DC/AC Converter
Renewable energy systems
Bidirectional DC/AC converters are commonly used in renewable energy systems such as solar photovoltaic (PV) and wind power systems. They convert DC power generated by renewable sources to AC power that can be fed into the grid and vice versa.
Uninterruptible power supplies (UPS)
Bidirectional DC/AC converters are often used in UPS systems to provide backup power in the event of a power outage. They can convert DC power from batteries to AC power to power critical loads, and can also convert AC power from the grid to DC power to recharge the batteries.
Energy storage systems
Bidirectional DC/AC converters are also used in energy storage systems such as batteries and supercapacitors. They can convert DC power from the storage system to AC power that can be used by the load, and can also convert AC power from the grid or renewable sources back to DC power to charge the storage system.
Grasen released the 300kW to 420kW ultra-fast charger with Max. output current 400A can charge a vehicle battery up to 80% in just 15 minutes.
As a local charging network operator, one of our customers from the Republic of Kazakhstan built this EV charging station with Grasen DC fast chargers, which are used to charge Tesla.
This charging station is located in North America. Customer ordered DC fast chargers with GB/T and CCS1 connectors.
Most DC chargers across North America are compatible with the CCS and CHAdeMO systems. However, while Tesla uses CHAdeMO stateside, it has switched to CCS (shown above) in Europe.
