A Non-linear Controller for Single-Phase AC-AC Power Converter to meet UPS Performance Index
This article focuses on AC-AC power converter that can be used for uninterruptible power supply (UPS). The converter is built on two stages: a AC-DC input stage and a DC-AC output stage. The two blocks are connected by an intermediate DC bus. The aim of control is threefold: i) power factor correction ii) regulation of DC bus iii) generating a sinusoidal voltage at the output. The synthesis of controllers has been achieved through the technique of nonlinear backstepping control. A detailed analysis of the stability control system is presented. The performances of regulators have been validated by numerical simulation in MATLAB / SIMULINK.
Keywords: UPS, AC-DC converter, DC-AC converter, power factor, Backstepping
