A zero voltage switching based three phase voltage source inverter is presented. The soft switched resonant pole which is obtained by generalizing the conventional pseudo-resonant pole, is presented and suitable control and modeling methods are also described. The three phase resonant pole inverter is easily obtained by connecting three resonant poles to voltage source in parallel and it can be...

Inverters designed using reduced active semiconductor devices can be of interest to the industry because of their lower cost and enhanced reliability linked to their less complex gating and control circuitries. In this paper a four switch three phase b-4 topology for the grid connected application in an effort to reduce the cost of the inverter is investigated. Admittedly, this topology warrant...

(Abstract) This dissertation aims to present a detailed analysis of the grid voltage disturbance in frequency domain for the current control design in the grid-tie inverter applications and to propose current control techniques in order to minimize its impact and maximize feasibility of the power conditioning system in distributed generations. Because the grid voltage is constantly changing, th...

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...

Inverters with reduced number of switches have been proposed in the literature to improve the capability of cost reduction, total inverters size and switching losses of dc/ac inverter topologies. In addition, they have a lower probability of damaging the semi-conductor switches as well as lower commonmode currents. This paper proposes new designs for inverters with reduced number of switches. F...

Abstract-A new control approach for three-phase gridconnected inverters is presented. The inverter stage is a standard three-phase half bridge. During each 60° of line cycle, the three-phase half bridge can be de-coupled into parallel-connected a dual-buck inverter. Based on Onecycle control, a Unified Constant-frequency Integration controller (UCI) is proposed for the dual-buck inverter. The c...

In this paper, four-switch inverter fed direct torque control three phase Induction Motor drive is presented. A triangular wave is used as dither signal of minute amplitude (for torque hysteresis band and flux hysteresis band respectively) in the error block. This method minimizes flux and torque ripple in a Four-Switch inverter fed induction motor drive while the dynamic performance is not aff...

This paper presents a model predictive control (MPC) of a utility interactive three phase inverter (TPI) for a photovoltaic (PV) system at commercial level. The proposed model uses phase locked loop (PLL) to synchronize the TPI with the power electric grid (PEG) and performs MPC control in a dq reference frame. TPI model consists of a boost converter (BC), maximum power point tracking (MPPT) co...

This paper presents a model predictive controlled three-level three-phase active neutral-point-clamped (ANPC) inverter for distributing the voltage stress among the semiconductor power switches as well as balancing the neutralpoint voltage. The model predictive control (MPC) concept uses the discrete variables and effectively operates the ANPC inverter by avoiding any linear controller or modul...
