What Does The Performance Of A Harmonic Filter Depend On?

The performance stability of the low harmonic vfd is affected by multiple factors, including load characteristics, network impedance, and filter parameter matching. For operating conditions with load fluctuations, active solutions can continuously adjust the output response under varying frequency and amplitude conditions, which is beneficial for maintaining performance in complex power grid environments. In contrast, for scenarios with smaller load changes and relatively clear requirements, the steady-state performance of the passive power harmonic filter still has engineering value; its simple structure facilitates predictability in long-term operation.
