This paper proposes replacement of silicon (Si) IGBT based multilevel inverters and interleaved boost converters with simpler power electronic topologies, using silicon carbide (SiC) power semiconductor devices, in medium voltage wind energy conversion system (WECS). For medium voltage WECS of 3-6kV and 2-5MW multilevel inverters and interleaved boost converter topologies are used. Simpler topologies...
Microgrid protection is one of the main challenges in the advancement of power system. The use of a static switch for microgrid protection is proposed by many researchers. But, in the present literature, the effects of power electronic protections of inverters on microgrid protection are overlooked. The inverter is protected from overcurrents by DESAT protection present in driver circuit. The static...
This paper proposes a matrix converter fed, sinusoidal input output high frequency transformer. A single phase three winding transformer is used in the proposed topology. The primary side of the transformer is connected to a low pass filter, and a three phase to single phase matrix converter. The two secondary windings of the transformer are connected to two low pass filters, and a three phase to...
This paper proposes a novel strategy of control of the active power flow from the power system grid to a micro grid by a power electronic transformer (PET), consisting of controllable loads and distributed energy resources (DER), both renewable and non-renewable. A 60 Hz, step down transformer is generally used at the Point of common coupling (PCC) of a micro grid to connect to the power system grid...
This paper presents a review of the current research in the area of ac/ac power conversion with power electronic transformer. The topologies considered have the following features: 1) generation of adjustable frequency and magnitude PWM ac voltage waveform from a balanced three-phase ac voltage source with a high frequency ac link, 2) bidirectional power flow capability, and 3) single stage power...
