The increase of transmission frequency reveals more merits than lowor medium-frequency distribution among different kinds of power applications. Highfrequency inverter serves as source side in highfrequency ac (HFAC) power distribution system (PDS). However, it is complicated to obtain a highfrequency inverter with both simple circuit topology and straightforward modulation strategy. A novel sw...

This paper presents the design, and simulation of a soft switched boost converter for a switched reluctance motor with a closed loop controller. A soft switching scheme is proposed in the converter with minimum components, which reduces the switching loss and stress across the switch so that the harmonic generation is reduced in the output. The switch used in this converter switched ON at zero ...

This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performan...

In this paper, a novel control strategy for a nonlinear boost inverter is proposed. The idea is based on generating an autonomous oscillator that does not need an external reference signal. This aim is achieved by using energyshaping methodology with a suitable Hamiltonian function which defines the desired system behavior. A phase controller is added to the control law in order to achieve 180◦...
