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...

In this paper a new SVPWM technique is implemented along with multilevel inverter topology for a four-pole induction-motor drive; which is constructed using the induction-motor stator winding arrangement. In this process we are comparing with the conventional five-level inverter topologies so we are a single dc source with a less magnitude therefore, the power balancing problem are reduced. As ...

This paper presents a methodology to apply a novel space vector pulse width modulation control for three phase Z-source inverter. The space vector modulation for the conventional voltage source inverter is modified so that the additional shoot-through states are inserted within the zero states. So zero voltage time period is diminished for generating a shoot-through time, and active states are ...

An overview of overcurrent and overvoltage CSI faults is presented and strategies, how to protect a CSI equipped with IGBT power switches against these failures are developed and explained. The shown strategies and the related circuits are applicable at low expense and require only minor changes in the CSI and its control.

This paper presents a single-phase Z-source inverter as a power conditioning system for a single phase utility connected system. Z-source inverter is a single-stage topology that has buck-boost feature, which is possible because of additional shoot through state introduced in zero state of the conventional inverter pulse width modulation and provides desired output AC voltage. Small distributed...

This paper presents a modified Current Source Parallel Resonant Push-pull Inverter (CSPRPI) for single phase induction heating applications. One of the most important problems associated with current source parallel resonant inverter is to achieve ZVS in transient intervals. This paper shows that the CSPRPI with integral cycle control method has dynamic ZVS. According to this method, it is the ...

Nowadays, inverters are power electronics devices used in the renewable energy conversion systems and also to fed induction motors, therefore the continuity of service of power converter has been a major concern. This paper presents a new approach of open circuit fault detection in a pulse width modulation three phase voltage source inverter. The fault occurrence detection was based on the stan...

In this paper, a novel unity power factor (UPF) hysteresis current control method for surface-mounted permanent magnet synchronous motor (SPMSM) drive system is presented. The optimum voltage vectors, which are selected from a switching table according to the magnitude and phase of the stator current vector, are applying to the voltage source inverter (VSI). The UPF operation for SPMSM is achie...

Inverters used as the interface for a distributed generator in a three-phase four-wire system sometimes operate with a large neutral current because of unbalanced loads and singlephase (possibly nonlinear) loads. Voltage balance within the dc-link of the inverter is important for proper operation of the inverter, and the neutral current is a significant disturbance to this. It is preferable to ...
