Description:

Harmonic treatment includes harmonic treatment cabinet and APFC harmonic treatment cabinet.

Moving to harmonic treatment cabinet for one-to-one local filtering, harmonic current content before treatment is 26-32%, mainly 5 times, 7 times, 11 times, a small amount of 13 times, etc. After treatment, it is mainly the 23rd and 25th harmonics and other high order harmonics. The harmonic voltage contains ThDUW 5%, and the harmonic current contains ThDIW 6% (when rated load output, THDZ^8% (when 50 magnetic load output).

APFC harmonic governance is based on the characteristics of high frequency switch power supply, in the high frequency switch power supply, dc 630 alas pressure there, we are not using three-phase rectifier bridge to form high pressure, but the way of PWM rectifier, and other harmonic waves in a different way, this way it series, in the middle of the main circuit itself is not the harmonics.

Power source APFC power factor corrector mode (P shed rectifier) can fundamentally solve the problem, it has little influence on each other, its effect is the best, in accordance with the scope of power grid specifications, is able to achieve harmonic current distortion THD < 5%, in practical application THD 43%, although relatively higher cost, But for high frequency switching power supply, APFC harmonic treatment scheme is also a more suitable harmonic treatment.
