Abstract:

A novel hybrid clamped dual-PWM three-level converter topology is proposed for induction motor drives in this paper. The switching states of hybrid clamp three-level converters increase to sixty-four from twenty-seven switching states of diode clamp three-level converters. In order to realize optimization of its redundant voltage space vectors by detecting voltage of clamp capacitor and difference of capacitor voltage in DC side, Generating an optimized switching pattern, The hybrid clamped three-level converter increases the voltage levels number, reducing the harmonics associated to the comm

Abstract:

Active power filter can compensate harmonic and reactive power, Three level neutral point clamp (ANPC) has the characteristics of low output harmonic and low device loss. The control of three-level active power filter needs to consider multiple objectives. Finite control set model predictive control (FCS-MPC) is a new method which can add constraints and multi-objective control. According to the limit of the switch state, it can track the reference current, which has the characteristics of fast dynamic response and good compensation effect. This method not only keeps the neutral point voltage

Abstract:

Considering the disadvantages of the traditional development pattern in an embedded control system for an inverter, that is, the single-process thinking and separation of software and hardware, a novel method, which is a model-based design, for developing a double closed-loop control system for the diode-clamped three-level inverter was proposed. System control models, including the PWM control algorithm model, the voltage control model, the neutral-point potential balancing model, and the frequency control model, were built with the MATLAB platform.

Abstract:

In this paper the standalone operation of the modified seven-level Packed U-Cell (MPUC) inverter is presented and analyzed. The MPUC inverter has two DC sources and six switches, which generate seven voltage levels at the output. Compared to cascaded H-bridge and neutral point clamp multilevel inverters, the MPUC inverter generates a higher number of voltage levels using fewer components. The experimental results of the MPUC prototype validate the appropriate operation of the multilevel inverter dealing with various load types including motor, linear, and nonlinear ones.

Abstract:

Different Half-Bridge (HB) converter topologies for an Integrated Voltage Regulator (IVR), which serves as a microprocessor application, were evaluated. The HB circuits were implemented with Stacked Transistors (HBSTs) in a cutting-edge 14 nm CMOS technology node in order to enable the integration on the microprocessor die. Compared to a conventional realization of the HBST, it was found that the Active Neutral-Point Clamped (ANPC) HBST topology with Independent Clamp Switches (ICSs) not only ensured balanced blocking voltages across the series-connected transistors, but also featured a more r

Abstract:

The major cause of sudden cardiac death (SCD) is ventricular arrhythmias due to unstable myocardial electrical activity in which the ATP-sensitive K+ (KATP) channels play a role. Genetic disruption of these channels predisposes the myocardium to arrhythmias. Two point mutations in the Kir6.2 subunit are found in SCD with acute myocardial infarction. Here we show evidence for the functional consequences of the P266T and R371H variants. Baseline single-channel properties, expression density, and channel modulations were studied in patch clamp. We focused on channel modulations by intracellular A

The minifilament arose in a negative-magnetic-polarity coronal hole. The Mg ii spectroheliograms verify that the minifilament plasma temperature is chromospheric. The Mg ii spectra show that the erupting minifilament’s plasma has blueshifted upflow in the onset of the jet spire and simultaneous redshifted downflow at the location of the compact jet bright point (JBP).

The combination of the clamp voltages corresponding to the four switch modes in each fault mode is determined uniquely.

SummaryFive‐level active neutral‐point‐clamped (5L‐ANPC) converters have great practical potential in the field of medium and high voltage variable frequency speed regulation.

In this paper, an improved self‐balancing voltage 5L‐ANPC topology (ISBV‐5L‐ANPC) is proposed to address such voltage balancing problem as series switches and high voltage leaps, which realizes dynamic and static voltage equalization by connecting the self‐balanc
