Significant reduction in PV inverter downtime: High-speed writing of FeRAM enables millisecond-level current and voltage logging.
The customer, a globally advanced company in environmental conservation that develops renewable energy equipment such as PV inverters, energy storage, and wind power generation facilities, has adopted FeRAM for their PV inverters.
The customer was required to log current and voltage data every second to ensure reliable fault analysis from end users. Traditional non-volatile memory such as EEPROM and FLASH memory faced challenges in maintaining operation over the long operational periods of the customer's products.
Therefore, by adopting FeRAM, which offers fast writing speeds and high rewrite endurance, the customer has successfully developed products that reliably store log data throughout the long operational lifespan, satisfying the demands of end users.
[Case Overview]
■ In PV inverters, FeRAM enables high reliability, ease of maintenance, and a long system lifespan due to its fast writing speeds, high rewrite endurance, and excellent data retention.
