The four-phase interleaved boost converter (PFC) is a cutting-edge circuit design that builds upon traditional boost converters. Unlike the original design, which operates in parallel, the PFC utilises an interleaved approach, where the number of parallel boost converters depends on the circuit load.
This innovative design addresses the issue of overload burden faced by the traditional boost converter, which often requires larger equipment and increased switch operation as the circuit load increases.
The PFC ensures improved performance, as well as reduced equipment size and switch operation load.

The three-phase active power filter (APF) is an advanced technology to compensate for higher harmonics in electrical systems.
This compensator utilises three first harmonic detectors (FHDs) to calculate the compensation currents (Ic). The compensation process involves subtracting the first harmonic component (IH1) from the load current (IL) to achieve a cleaner and more stable output.
The compensation reference signal (ICr) is a reference for the output current controller, which controls the output inverter transistors in conjunction with pulse width modulation (PWM).
This solution eliminates the negative effects of harmonic distortion, such as decreased efficiency, increased equipment wear and tear, and power quality issues.
