Such power factor correction techniques rely on the use of power electronics, controlled using analog or digital controllers.ĭigital power factor correction control design using Simulink ® lets you make use of multirate simulation to design and tune digital control algorithms, enabling you to tailor the input current waveforms, thus keeping losses low while improving the power quality to a desired value. However, nonlinear loads generating harmonics require power factor correction techniques like tuned or active harmonic filters to mitigate these harmonics and improve power quality.

Power factor improvement for linear loads can be brought about by reactive power compensation to compensate for the leading or lagging VARs. This increases the total harmonic distortion of load current, thereby decreasing the power quality.Įngineers use different techniques to improve power quality for such electrical installations. However, one disadvantage of a switched-mode power supply without power factor correction is that it introduces these harmonics in the load current due to switching from semiconductor devices such as MOSFETs. The deployment model has a real-time interrupt service routines (ISR) configured to trigger PFC control at the rate of 50 kHz.For example, loads like switched-mode power supplies are widely used because of the advantages they offer in the terms of size, cost, and efficiency.

Therefore, Power Factor Correction (PFC) is necessary for AC-DC. The controller operates at a rate of 50 kHz.ġ. These strategies are implemented in MATLAB/SIMULINK and the performance of the proposed. The output of the PFC controller is the PWM duty cycle of the DC-DC boost converter. Key Words: Wireless charging system, Buck-Boost Converter, Proportional-Integral controller (PI), Power factor correction (PFC). The process is modeled using the MATLAB Simulink model of closed-loop operation. The reference for the current loop is generated by feed-forward of the rectified DC voltage as well as the output of outer the voltage loop. achieved through the power factor controller circuit working in continuous conduction mode of converter.

The inner current loop performs the wave shaping of the input AC current to maintain a high power factor. The outer voltage loop ensures that the output DC voltage is maintained at the set reference by using a discrete proportional integral PI controller. The PFC controller provides current shaping of the AC input and regulates the DC bus. The duty cycle of the PWM output determines the amount of boost imparted to the input voltage. Digital power factor correction control design using Simulink lets you make use of multirate simulation to design and tune digital control algorithms, enabling. For simplicity, only one phase has been used for the boost operation. &0183 &32 Matlab Projects, High Efficient Bridgeless Three-Level Power Factor Correction Rectifier, metal oxide semiconductor field-effect transistor (MOSFET), electromagnetic interference, three-level PFC rectifier, Matlab Source Code, Matlab Assignment, Matlab Home Work, Matlab Help.
