Abstract:-Three-phase rectifier topology with active current injection for improved power quality and high
efficiency. The proposed rectifier consists of a boost-type power factor correction stage and a three-phase
diode rectifier with a midpoint connection. The active current injection is implemented using a fourth leg
with a high-frequency switching converter, which injects a controlled current to balance the input current
waveform and reduce the harmonic content. The rectifier topology and control strategy are presented in
detail, and simulation and experimental results demonstrate the improved power quality and high efficiency
of the proposed system. The proposed rectifier is suitable for a wide range of applications, including
renewable energy systems and electric vehicles.
Three-phase rectifiers are commonly used in various applications, such as motor drives and power supplies.
The efficiency of these rectifiers plays a vital role in determining the overall performance of the system. One
of the significant challenges in designing three-phase rectifiers is the high harmonic distortion caused by the
switching action of the power devices. To overcome this issue, various control strategies have been proposed,
including active current injection.
Active current injection is a well-known control technique that can be used to reduce the harmonic distortion
and improve the efficiency of three-phase rectifiers. In this technique, a low-frequency voltage signal is
injected into the rectifier's control circuit to control the switching of the power devices. This helps to reduce
the harmonic content of the output voltage and current, resulting in a more efficient and reliable
system
