This paper introduces eight novel interleaved non-isolated dc-dc converters with ultra-high step-up and zero voltage switching (ZVS) capabilities for renewable energy systems. To increase the gain, proposed benefit coupled inductors, high-frequency (HF) transformer, multiplier (VM) techniques. In comparison to other converters, which just inductors or HF transformers, these combinations of tech...

For medium voltage, high power applications 3-phase neutral point clamped AC-DC multilevel converters are becoming a good choice. In this paper the performance of a 3-phase neutral point clamped Active Front End three level converter for high power application with simplified control scheme is presented. A complete mathematical model of the control scheme is developed and performance is investi...

This paper presents a proposed five-level inverter based on conventional Neutral Point Clamped (NPC) topology which is type of Multilevel Inverters (MLIs). MLI great solution for high power application in addition to medium power, low and renewable energy applications. The reduces the number input DC sources as compared with five level NPC topology. Also, this circuit conduction losses by reduc...
