“…However, the sine PWM method reduces the DC bus utilization to V dc 2 of the phase voltage, which, in turn, reduces the performance of the MC. To increase the DC bus utilization by a factor of 2 √ 3 , a third harmonic zero-sequence component is used to modify the duty cycles of the legs in [19][20][21], as given by Eq. (24).…”

The conventional sinusoidal pulse width modulation (SPWM) and the space vector PWM (SVPWM) switching techniques are widely used for power converters due to their ability to control the harmonic content of the output voltage. The most popular PWM techniques used in matrix converters are direct space vector modulation (DSVM) and indirect space vector modulation (ISVM). Since these techniques are complex and difficult to implement, there is demand for a PWM technique with minimum computation to operate matrix converters continuously. In this paper, decoupled indirect duty cycle (DIDC) PWM technique is proposed for the conventional matrix converter (CMC). This technique eliminates the duty cycle computations required for every switching period. In addition, the carrier frequency adjustment technique (CFAT) is proposed to improve the quality of both output voltages and input currents. A MATLAB-Simulink-based simulation proves the efficiency of the proposed algorithms, and an experimental setup is developed to validate them.

Owing to the increasing demand in the urban areas for new technologies such as heat pumps and electric vehicles (EVs), greater power capacity in low voltage (LV) distribution networks is becoming increasingly important. This study will investigate how to improve the power capacity through the implementation of point of use voltage regulation (PUVR). PUVR relies on a power electronics converter at each end-user. Most LV network cabling has a voltage limit of 1 kV, PUVR exploits this voltage rating to increase the network capacity. This study will describe and discuss the results from a viability study using data from a utility company, which shows that the capacity in the LV network could be increased by an additional 500 kVA. However, it was also found that PUVR using present off-the-shelf converters is not as cost-effective as replacing the LV network cables. Two power electronics topologies have been investigated in the simulation studies to date: the AC chopper circuit and the back-to-back inverter circuit. These two topologies were compared and the AC chopper was found to be a cheaper, more efficient topology. Therefore the AC chopper is more suitable for this application and may increase the viability of the PUVR

Data centers (DCs) are considered critical loads that require premium power from utilities to ensure reliability at all times. Microturbine (MT) generation systems are becoming important in DCs, not only as distributed generation (DG) for supplying electricity, but also for providing cooling and heating functions, which is known as combined cooling, heat and power (CCHP) or tri-generation. This paper considers the use of an indirect matrix converter (IMC) as the power electronic interface (PEI) to connect a permanent magnet synchronous generator (PMSG) with the power grid in a DC. First, the paper analyzes the semiconductor losses for the IMC and the conventional back-to-back converter (BBC) as a function of the switching frequency in order to determine the favorable operating conditions for the IMC. It then presents a new control strategy that does not require measuring the grid voltages to inject the commanded power into the grid at unity power factor. Simulation results of a 15-kVA, 480-Vrms IMC-based MT generation system show the effectiveness of the proposed control technique for this particular application.
