6 FAQs about The impact of high frequency on inverter

Do high frequency harmonics increase Eddy loss in a PV inverter?

Simulation and practical results have evaluated this factor in different conditions. Current harmonics higher than 2 kHz from PV inverter highly contribute in Kf value. Field measurements show that high-frequency harmonics can increase eddy losses by 33%. The loss due to higher frequency harmonics causes 22% acceleration in ageing.

Do high frequency harmonics affect the temperature rise of a transformer?

Although the existing standards mainly consider the impact of harmonics up to 2 kHz, higher frequency harmonics generated by high power converters utilized in renewable energy sources can also contribute to the temperature rise of a transformer.

What is the switching frequency of a small-size inverter?

The measurements show that the switching frequency of small-size inverters in system 1 is in the range 16–17 kHz, whereas in system 2, it is around 3 kHz, which could be a source of difference in Kf Hf levels measured in these systems.

Do high frequency harmonics increase Eddy losses?

Field measurements show that high-frequency harmonics can increase eddy losses by 33%. The loss due to higher frequency harmonics causes 22% acceleration in ageing. The level of current harmonics circulating in a transformer winding can affect its operating temperature and lifetime.

Do current harmonics affect distribution transformer K-factor?

Impact of current harmonics on distribution transformer K-factor is investigated. Simulation and practical results have evaluated this factor in different conditions. Current harmonics higher than 2 kHz from PV inverter highly contribute in Kf value. Field measurements show that high-frequency harmonics can increase eddy losses by 33%.

Do high-frequency current harmonics cause a large transient?

However, comparing the values of Kf Hf and Kf Lf indicates that a significant level of high-frequency current harmonics created Kf Hf values up to 40 during transient times in this system. As can be seen from Fig. 7 (c), no large transient happened during the measurement period for system 3.
