The fly back converter has been widely used for multi outputs due to the simple structure and low cost in low-power applications. This paper presents a new multi output converter. It consists of a half-bridge inverter with boost converter in primary side and a fly back rectifier that is integrated with an auxiliary buck converter in secondary side. The boost converter is used to generate high v...

The Modular Multilevel Converter (MMC) represents an emerging topology with a scalable technology making high voltage and power capability possible. The MMC is built up by identical, but individually controllable sub modules. The Modular Multilevel Converter (MMC) is a new topology for multilevel converters with potential for medium voltage and high voltage applications. Equivalent Circuit mode...

This paper deals with the design and analysis of standalone solar PV based boost converter with P& O (Perturb and Observe) MPPT (Maximum Power Point Tracking) Techniques. An intermediate converter can therefore increase efficiency by matching the PV system to the load and by operating the solar cell arrays at their maximum power point. MPPT (Maximum Power Point Tracking) controller is used for ...

We discuss an estimation and simulation framework for energy efficient application design using platform FPGAs. This framework integrates various widely used simulators available for platform FPGAs, allows specification of kernel designs as a set of libraries, and enables efficient application design through the integration of high-level performance estimators and design space exploration tools...

Ambient light sensors have been used to reduce power consumption of Active Matrix Liquid Crystal Displays (AMLCD) adjusting display brightness depending on ambient illumination. Discrete sensors have been commonly used for this purpose. They make module design complex. Therefore it has been required to integrate the sensors on the display panels for solving the issue. So far, many kinds of inte...

We demonstrate that 80 Gb/s data-packets can be all-optically switched into two different ports employing an optical wavelength converter controlled by a monolithically integrated optical flip-flop memory. The optical wavelength converter consists of a semiconductor optical amplifier and an optical filter. The integrated optical flip-flop exhibits single-mode operation, has 35 dB contrast ratio...

Stable triggering of acquisition devices is critical to accurately measure electromagnetic transients, especially for very fast transient overvoltages (VFTOs). A highly stable and low-cos t self-trigger method measurement proposed. An integrated low-voltage arm module was developed synchronously realise the VFTO measurement. The trigger branch using a high-pass filter. This component obtained h...

In order to equip more high-energy pulse loads and improve power supply reliability, the vessel integrated system (IPS) shows an increasing demand for high-voltage large-capacity energy storage systems. Based on this background, paper focuses a super capacitor based cascaded DC-DC converter composed of modular multilevel (MMC) dual active bridges (DAB). The is called MMC-DAB short. This analyze...

he Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) program is the fi rst to use the Integrated Electronics Module (IEM) spacecraft architecture. The IEM is based on the idea of incorporating the electronics for several spacecraft subsystems into a single chassis using plug-in cards. In addition to the space and mass savings realized with this approach, the concept can be ad...
