High frequency inverter arcing

Do high frequency arcs cause lower arc power?

High frequency arcs exhibit a similar characteristic to lower frequency arcs. A reduction in pressure results in lower arc voltage and arc power. Arcing tests at atmospheric pressure may therefore represent a worst-case scenario and the development of a low-pressure test environment may not be necessary.

What is a high frequency arc?

As such, arcs with a peak current up to 4.6 kA are generated at frequencies in the range of 0.5-2 kHz using an underdamped RLC circuit, under pressures of 0.2-1 bar absolute. High frequency arcs exhibit a similar characteristic to lower frequency arcs. A reduction in pressure results in lower arc voltage and arc power.

Can DC arcing protect the inverter and photovoltaic system?

This paper presents a protection solution based on DC arcing test that monitors and analyses DC arcing to protect the inverter and the photovoltaic system. The test results show that this solution can effectively improve the reliability and safety of the inverter, avoiding equipment damage and accident caused by DC arcing. 01. BACKGROUND

How to adjust the ad_result of a non-arcing inverter?

Select B and I in a way that the inverter switching frequency is outside the frequency band defined by B and I. In case there are high AD_Result values also during non-arcing, increase parameter D to 0.1 or 0.2 or adjust the cutoff frequencies of the analog band-pass filter.
