Abstract

For the control design of a UPS, a common assumption is to consider the associated filter and the load as linear as a time invariant system. This paper presents a single phase inverter controlled by the nonlinear passivity technique. The aim is to achieve a nonlinear control providing good dynamic response, robustness and stability to the filter and inverter
