summary
The hybrid harmonic filter (HHF) absorbs harmonics generated in six-pulse nonlinear loads of inverter, UPS, and elevator, and meets the limits of voltage distortion (Vthd) and current distortion (Ithd) of IEEE Std. 519 in preload area. The product reduces an inductor capacity to a half of existing band-pass filter, and a filter condenser capacity to 1/3. Therefore, it is an easy-to-install filter for six-pulse nonlinear load, securing cost effectiveness.
