PROJECT TITLE :

Enhanced Automatic-Power-Decoupling Control Method for Single-Phase AC-to-DC Converters - 2017

ABSTRACT:

Existing control schemes for single-section ac-to-dc converters with active power-decoupling perform usually involve a fervent power-decoupling controller. Due to the highly coupled and nonlinear nature of the one-part system, the look of the ability-decoupling controller (sometimes primarily based on the tiny-signal linear control techniques) is cumbersome, and the management structure is difficult. Additionally, with the existing power-decoupling management, it's exhausting to attain satisfied dynamic responses and robust circuit operation. Following a recently proposed automatic-power-decoupling management scheme, this paper proposes a nonlinear management method which will achieve enhanced large-signal dynamic responses with sturdy disturbance rejection capability without the need for an infatuated power-decoupling controller. The proposed controller encompasses a easy structure, of that the design is simple. The control methodology can be simply extended to different single-phase ac-to-dc systems with active power-decoupling perform. Simulation and experimental results validate the feasibility of the proposed management method on a 2-switch buck-boost PFC rectifier prototype.
