This paper presents a compensation method of dead time effects in a grid-tied single-phase inverter. In general, output current of grid-tied inverter contains odd-numbered harmonics because of dead time and nonlinear characteristics of the switching devices. Thus, in this paper, effects of dead time in output voltage and current are analyzed in detail. Also, a new compensation algorithm using Second-order...
In single-phase grid-connected inverters, precise and fast detection of the phase angle is essential to guarantee the correct generation of the reference signals. In order to detect the phase angle, SRF-PLL system has been widely used in the grid-connected inverter. However, in contrast with three-phase grid-connected inverter system, single-phase grid-connected inverters are difficult to acquire...
