A Class E Power Amplifier with Low Voltage Stress
2015A 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.

A high-voltage DC-DC converter with low-voltage stress and output current tripler
2006 37th IEEE Power Electronics Specialists Conference, 2006A high-voltage dc-dc converter with low voltage stress on the switches and output current tripler is presented in this paper. This converter exhibits three distinct features. First, the voltage stress on the switches is only one-third of the input voltage, so that switches of low voltage rating and thus of low on-resistance can be used. This can reduce

High-Voltage Gain Half-Bridge Z-Source Inverter With Low-Voltage Stress on Capacitors
IEEE Transactions on Industrial Electronics, 2017In this paper, a new topology for half-bridge Z-source inverter is proposed. The proposed topology has only one impedance network. Unlike to the conventional half-bridge inverter, the proposed topology can provide zero voltage level at the output. It also increases output voltage level and stabilizes it in the desired value. Capacitor voltage stress in

A Novel Transformer-less Adaptable Voltage Quadrupler DC Converter with Low Switch Voltage Stress
IEEE Transactions on Power Electronics, 2014In this paper, a novel transformer-less adjustable voltage quadrupler dc-dc converter with high-voltage transfer gain and reduced semiconductor voltage stress is proposed. The proposed topology utilizes input-parallel output-series configuration for providing a much higher voltage gain without adopting an extreme large duty cycle.

Study on the Z-Source Inverter with Low Voltage Stress
Applied Mechanics and Materials, 2013This paper proposed a kind of low voltage stress Z-source inverter topology. In the topology, the inductors of Z-source can be connected alternatively in parallel during the time of shoot-through and in series during the other time. Thus the network can obtain a high boost factor with a small shoot-through duty ratio and can decrease the voltage stress

Low voltage stress-induced leakage current in HfO2 dielectric films
Materials Science and Engineering: B, 2010Abstract The conduction mechanism and the behavior of stress-induced leakage current (SILC) through the HfO 2 high- k layers in metal-oxide-semiconductor (MOS) structures have been investigated. Assisted tunneling of electrons via stress-induced interface traps and bulk oxide traps are responsible for the SILC generation in HfO 2 dielectric.

A low voltage micromachined optical switch by stress-induced bending
Technical Digest. IEEE International MEMS 99 Conference. Twelfth IEEE International Conference on Micro Electro Mechanical Systems (Cat. No.99CH36291), 1999In this paper, a novel electrostatically actuated 2/spl times/2 fiber optic switch with very low operating voltage is presented. Using stress-induced bending of polysilicon plates, a vertical mirror is raised above the substrate. Electrostatic force is used to attract the mirror to the substrate to switch between the cross and the parallel states of ...

Reliability of porous low-k dielectrics under dynamic voltage stressing
2012 IEEE International Reliability Physics Symposium (IRPS), 2012We investigate porous low-k SiCOH under dynamic voltage stress to provide new insights into electrical breakdown. Our results are consistent with the existence of two breakdown mechanisms: the first is independent of trench barrier material and other processing details and is identical for DC, unipolar and high frequency bipolar (AC) stress.
