SST SYSTEM (3KW)

SST SYSTEM (3KW)

The Solid State Transformer (SST) power transformer system is based on DAB converters with a high-frequency transformer. The system allows continuous operation with a power of up to 10 kW. SST features bidirectional energy transfer and "galvanic" isolation provided by the high-frequency transformer.

Project executed by SB Łukasiewicz - Institute of Electrical Engineering.

DAB Converter with Power PNOM = 3kW
Power Supply 1-phase active rectifier
Load 1-phase voltage inverter
Input Voltage UDC[IN] 400V
Output Voltage UDC[OUT] 400V
Maximum Input Current IIN MAX 8A
Maximum Output Current IOUT MAX 8A
Efficiency ≥95% at PNOM
Output Voltage Ripple ±5V
Output Voltage Regulation Accuracy ±5% UDC(OUT)MAX
Output Current Regulation Accuracy ±3% I(OUT)MAX
Switching Frequency 40 kHz/125 kHz

Product manufactured in the SiCharge project co-financed by NCBIR, project number TECHMATSTRATEG 1/34 7452/1/NCBR/2017.
