The emerging switched-capacitor-based multilevel inverters offer interesting merits such as self-balancing of capacitor voltages and boosting voltage gain. While the switched capacitors (SCs) in these topologies are charged parallel with dc source, severe current spikes issue is inevitable, rendering them impractical at high power. This article proposes a novel T-type inverter that mitigates by...

Abstract At present, the voltage level of a commercial SiC MOSFET can hardly meet requirements high-voltage field. For sake achieving application MOSFETs in fields, method series-connected has become practical and effective solution. However, multiple face problem unbalance, especially dynamic unbalance. Generally, unbalance could be solved using load side sharing schemes or methods gate side. ...

Three-legs active power decoupling (APD) converters are widely studied in the single-phase grid-connected systems to enhance circuit lifetime by creating an alternative path for typical existing dc-side pulsating ripple. Therefore, this reduces requirement of smoothing dc capacitors allowing compact designs even with implementation long life metalized film technology. In article, allow enhancem...

a new output structure for class e power amplifier (pa) is proposed in this paper. a series lc resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. this resonator causes low impedance at the second harmonic. the output circuit is designed to shape the switch voltage of the class e amplifier and lower the voltage stress of the transistor. t...

This paper proposes three phase Seven Level Cascaded H-Bridge Multilevel Inverter by using PD, POD, APOD, INVERTED SINEWAVE methods based on Sinusoidal PWM control techniques. There are 3 types of multilevel inverters named as diode clamped multilevel inverter, flying capacitor multilevel inverter and cascaded multilevel inverter. Compared to diode clamped & flying capacitor type multilevel inv...

In the rhythmically active pyloric circuit of the spiny lobster, the synapse between the lateral pyloric (LP) neuron and pyloric constrictor (PY) neuron has an inhibitory depressing chemical and an electrical component. To understand how the dynamics of the LP-->PY synapse affect the relative firing times between these two neurons in an ongoing rhythm, we characterized the dynamics of the LP-->...

In this paper, the weighted sum of spatial gradients, or WSSG (formerly known as composite velocity) is developed for use in active structural acoustic control (ASAC) on clamped flat rectangular plates. In previous work, WSSG was developed on a simply-supported flat rectangular plate\cite{pseudo}, and showed promise as a control metric. The displacement on the clamped plate has been modeled usi...

The graphene nano-electro-mechanical switches are promising components due to their outstanding switching performance. However, most of the reported devices suffered from a large actuation voltages, hindering them from the integration in the conventional complementary metal-oxide-semiconductor (CMOS) circuit. In this work, we demonstrated the graphene nano-electro-mechanical switches with the l...
