Three-Phase Diode Bridge Rectifier With Low Harmonics

This book reviews numerous research papers published in the last fifteen years in the area of current injection based rectifiers. A partial list of coverage includes principles of current injection; analysis of various magnetic current injection devices; the third harmonic current injection is discussed next, and several current injection networks are analyzed.

Several current injection networks that provide the optimal current injection are proposed, and some parasitic effects are discussed. Recovery of the power taken by the current injection networks is analyzed, and two types of passive resistance emulators are analyzed in detail, the current-loaded resistance emulator, and the voltage-loaded resistance emulator.

Avoiding the inductor of the current injection network results in mutipulse operation of the current injection based rectifiers with passive resistance emulators, which is discussed next.

In a separate chapter, a different current injection device based on three bi-directional semiconductor switches is presented, and previously derived results are generalized for this special type of current injection device.

Finally, the results are generalized to three-phase full-bridge thyristor rectifiers.
