6 FAQs about [Sic photovoltaic inverter efficiency]

Why do we use sic devices for PV inverters?

Cost is the key issue for widely usage of SiC devices for PV inverters , , , , . Due to the increased efficiency, the manufacturing and operating cost of PV inverters can be reduced by using SiC devices.

Is sic based PV inverter better than silicon based?

According to the comparison in Table 8 from the study, a SiC based PV inverter performed better than a silicon based PV inverter with less than one-third the weight and half the physical dimension [Data Courtesy: CREE Inc. and KACO – new Energy Inc.]. Table 8.

What are the advantages of SiC-based PV inverter?

By using advanced TIM, direct liquid cooling technology, heat sink, etc., the junction temperature of SiC devices can be reduced, and the reliability of PV inverters can be improved. Besides, high speed control algorithm and hardware board, dead-time optimization, high-frequency magnetic elements, etc., are very important for SiC-based PV inverter.

Can SiC diodes improve PV inverter efficiency?

Future work is planned to improve the EU and CEC weighted efficiency to >98.5%, such as reported for high cost PV inverter prototypes that use SiC MOSFET and SiC diode power devices [20, 21]. The planned efficiency improvements are achievable by pairing the SiC diodes with IGBTs that are optimised for high-speed switching.

Does a sic PV inverter have a short-circuit capability?

Short-circuit capability A SiC PV inverter may suffer hard-switching fault and fault under load. SiC devices should have short-circuit capability. However, the acceptable short-circuit time is limited and related to dc voltage .

How can inverter power filters reduce the cost of SiC power devices?

Manufacture inverters with a traditional switching frequency range, but higher permitted losses in the power filters. The inverter power filters can be reduced in size, weight, and cost. The reduction in the cost of the power filters can offset the increased cost of the SiC power devices.
