This paper proposes a simple control method of induction motors (IMs) with improved dynamic response and steady-state performance by using a model-based predictive control algorithm. The predictive torque control (PTC) method analyzes the relationship between the electrical torque and stator voltage of IMs by using the stator voltage vector magnitude to obtain the reference voltage vector angle and...
This paper proposes modulation and control strategy for a single-phase to three-phase (1p-3p) indirect matrix converter (IMC) drives. The 1p-3p IMC is composed of a singlephase current source rectifier (1p-CSR) and a three-phase voltage source inverter (3p-VSI). The 3p-VSI is operated with modulation strategy similar to that of a common inverter. The 1p-CSR must be operated with a restriction where...
This paper proposes a control strategy for the mono converter dual parallel (MCDP) surface-mounted permanent magnet synchronous generator (SPMSG) in the wind power generation (WPG) system. Since the MCDP SPMSG in the WPG system means that two generators are connected to the mono converter in parallel, it can reduce the cost and simplify the configuration of the WPG system compared to fundamental power...
This paper proposes a low voltage ride through (LVRT) control strategy for energy storage systems (ESSs). The LVRT control strategies for wind turbine systems and photovoltaic systems have been researched until now. Regardless of the energy source, the main aim of the LVRT control strategies for a grid side converter is to inject the reactive power according to the gird code regulations. The main...
This paper proposes a discontinuous pulse width modulation (DPWM) method for an indirect matrix converter (IMC) driving induction motor (IM) in order to reduce switching losses. The IMC has advantages that long lifetime and reduced volume depending on the lack of capacitors. However, the IMC has many electric switching devices because it is composed of two stages such as a rectifier stage and an inverter...
Using a Vienna rectifier as the machine-side rectifier of back-to-back converter is advantageous in terms of size and cost compared to three-level topologies and for this reason, the Vienna rectifier has been used in Wind Turbine Systems (WTS). This paper proposes a Model Predictive Control (MPC) method for the Vienna rectifier used in WTS with a Permanent Magnet Synchronous Generator (PMSG). The...
This paper proposes a control method for a reverse matrix converter (RMC)-fed three-phase permanent magnet synchronous motor (PMSM). In this regard, a direct power control (DPC) is used as an additional control method. An indirect matrix converter (IMC) is an AC/AC power conversion system without dc-link energy storage elements such as capacitors or inductors. The IMC features full four-quadrant operation...
This paper proposed control strategy of induction motor (IM) fed by indirect matrix converter (IMC) in reverse power mode. The IMC is an AC/AC power conversion system without dc-link energy storage elements as bulky capacitor or inductor. For this reason, the IMC has many advantages that compact, low weight and durability. Furthermore, it features full four quadrant operation and sinusoidal input...
This paper proposes a three-phase input indirect matrix converter topology for a dual ac-drive system with modified switch control schemes, along with addition of a leg. This topology is developed based on a very sparse matrix converter with addition of a leg in the inverter stage, which can reduce the amount of power transistors compared to the conventional dual matrix converter system and; therefore,...
