A high-efficiency system for conducting power factor (PF) and harmonics correction in an electrical network, comprising a controller; a digital PFC capacitor array comprising two or more passive PFC capacitors, providing fine steps increments in the PF correction; and linear PFC capacitor arrays, providing coarse steps increments in the PF correction. The PF correction in coarse steps increments and fine steps increments allow a total or near total PF correction without overcompensation. Optionally, the system further comprises a lower power active power filter (APF) configured to only target and eliminate or minimize harmonics in the electrical network.
