Design and Control of a Novel hybrid Active Power Filter based on Load Harmonic Currents Separation with the aim of DC-link voltage minimization in voltage source converter
This paper proposes a new hybrid active power filter, including voltage source converter (VSC) based active power filter and Thyristor Controllable LC Passive Filter (TCLC-HAPF) for eliminating harmonic load current components and compensating reactive power. This new structure which is based on the separation of high and low-frequency components of load current idea can reduce the drawbacks of...
متن کاملAdaptive PID Control of DC-link Voltage via DC/DC Buck-Boost Converter
Thammasat International Journal of Science and Technology, Vol. 18, No. 2, April-June 2013 42 Abstract Mainly, a photovoltaic (PV) system is able to generate wide ranges of voltage and current at terminal output. However, a PV cell is required to functionally maintain a constant direct current (DC) voltage at a desired level during real-time variations of incident light illumination and ambient...
متن کاملVoltage Equalization of DC Link capacitors in a CHB-Based PET under the Unbalance Voltage Conditions
The unbalance currents injection by power electronic transformers in order to improve the unbalance voltage conditions of the network causes an imbalanced voltage in the DC link capacitors and creates an active powers inequality in the different phases. In this paper, the proposed control structure independently controls the active power of each phase by modifying the power angle between the vo...

متن کاملA DC Voltage Control Strategy for Active Power Filter
Abstract: Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation p...
