The optimal voltage hysteresis current control of shunt active power filter
SU Shi ping 1  2  LI Sheng yi 2
Abstract:
The work principle of shunt active power filter and the characteristic of common hysteresis current control method are introduced briefly.A novel optimal voltage hysteresis current control technique is suggested to overcome the defect of common hysteresis current control and analyzed in detail.Its notable strongpoint is that it avods the complicated calculation and unnecessary switching of voltage source inverter by identifying the locations of reference voltage vector and current error vector to control the filter's outputs.It is fast and accurate and improves greatly the performance of shunt active power filter.
Key words:  active power filter,hysteresis current control,optimal voltage
