A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

The present work deals with the modeling and the stability analysis of the cascaded converters. When a converter tightly regulates its output, it behaves as a constant power load (CPL). The problem of CPLs is that they show negative incremental resistance that causes instability in the system because the control to output transfer function possessed a RHP pole. Hence the CPL has been modeled an...

The fly back converter has been widely used for multi outputs due to the simple structure and low cost in low-power applications. This paper presents a new multi output converter. It consists of a half-bridge inverter with boost converter in primary side and a fly back rectifier that is integrated with an auxiliary buck converter in secondary side. The boost converter is used to generate high v...
