An integrated H-bridge circuit in a HV technology

2016 IEEE 7th Latin American Symposium on Circuits & Systems (LASCAS), 2016
H-Bridges are well known circuits to connect a load to a DC supply in both forward/reverse bias. These circuits are commonly used to drive DC and stepper motors among many other power electronics applications. In this work, a fully integrated 12V H-Bridge is designed in a 0.6μm HV technology as a replacement of an obsolete commercial part.

H-bridged alternatives to the homologues of cyclopropane

Journal of Molecular Structure: THEOCHEM, 1996
Abstract Alternative H-bridged structures (6, 7 and 8) for homologues of cyclopropane (1) have been calculated using ab initio MO methods at the MP2/6-31G∗ and MP2/LANL1DZ levels.The energy difference between the classical structure 1 and its bridged analogue 6 decreases in going from C to Pb (1 vs. 6: C 197.0, Si 84.0, Ge 36.0, Sn −1.7, and Pb −45.4

An Optimize Configuration of H-Bridge Multilevel Inverter

2021 1st International Conference on Power Electronics and Energy (ICPEE), 2021
A traditional H-bridge inverter requires a minimum of four controllable switches and this multiplies with the levels in the inverter output voltage goes up. This work represents an improved multilevel inverter with a reduced number of switches. An improved structure using the sub-multilevel concept is proposed for a five-level inverter. This modified H-

Outline of the Control Design for a Cascaded H-Bridge STATCOM

2008 IEEE Industry Applications Society Annual Meeting, 2008
The cascaded H-bridge converter (CHC) topology is ideal for implementation of direct connection static compensators (STATCOMs). However the topology requires significantly different control strategies as compared to conventional two level transformer connected STATCOMs and other multilevel STATCOMs. This paper outlines all aspects of a novel controller

Cascaded H-bridges for sub-module PV microinverter

2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016
In the recent years growing interest has been given to photovoltaic (PV) microinverters. Sub-modular optimization of PV panels where the junction-box of the panel is removed and each sub-modules is connected to an individual DC-DC converter realizing independent MPPT is one promising solution especially for systems subject to partial shading.

An Adjustable Sensorless Shoot-Through Protection for H-Bridges

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
The converters relying on H-bridge configurations exhibit complementary “symmetrical” switching devices for which a triggering dead-time must be considered in order to prevent shoot-through faults. There are two ways in which such dead-time is usually added to the bridges' input signals; namely, from the switching program itself, and by using dedicated

Simulation of a transistor clamped H-bridge multilevel inverter and its comparison with a conventional H-bridge multilevel inverter

2014 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2014], 2014
Double reference single carrier modulation technique is a new technique employed for generating pulses for multilevel inverters. This paper presents a simulation of a transistor clamped H-bridge multilevel inverter using double reference single carrier modulation technique.

Design of H-bridge multilevel active rectifier for traction systems

IEEE Transactions on Industry Applications, 2003
This paper is focused on the design of the controller for a high voltage-high power single phase front-end rectifier stage, for a large electric drive designed for, but not limited to, traction field applications. The rectifier should absorb current with low harmonic content to eliminate disturbances on the communication equipments and more generally ...

BIFURCATION ANALYSIS IN A PWM CURRENT-CONTROLLED H-BRIDGE INVERTER

International Journal of Bifurcation and Chaos, 2011
This paper introduces the complete bifurcation analysis in a PWM current-controlled H-Bridge inverter in a wide parameter space. First, we briefly explain the behavior of the waveform in the circuit in terms of the switched dynamical system. Then, the consecutive waveform during the duration of the clock interval is exactly discretized, and the return ...
