6 FAQs about [Capacitor compensation management]

How a capacitor compensation circuit is controlled?

Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.

Active compensation capacitor management (ACCM) With the proposed ASSF, the power-efficient fast loop is achieved by pushing pGATE adaptively. The precision-adjusted loop is also optimized to improve load transient recovery time and middle-frequency PSR by the proposed ACCM.

What is series capacitive compensation method?

Abstract: Series capacitive compensation method is very well known and it has been widely applied on transmission grids; the basic principle is capacitive compensation of portion of the inductive reactance of the electrical transmission, which will result in increased power transfer capability of the compensated transmissible line.

How a capacitor is calculated based on power factor?

In the first step, given power factor of each load node is predetermined and then capacitor at the load node is calculated based on the known power factor, active power, and reactive power of the load. In the second step, the total compensation power of all capacitors at electric loads is determined.

How to compensate for reactive current caused by EMI capacitor?

There is a novel method to actively compensate for the reactive current caused by the EMI capacitor. Moreover, the PFC current-loop reference is reshaped at the AC zero-crossing to accommodate for the fact that any reverse current will be blocked by the diode bridge. Both PF and THD are improved as a result. Figure 3.
