Photovoltaic power conversion with efficiency weight optimisation
IEEE International Conference on Industrial Technology, 2003, 2004Photovoltaic power conversion systems for power rating of about 2.5 kW consist generally of a step-up converter, a DC-AC inverter for 5 Hz and the transformer coupling to the grid. Potential separation is required between the modules and grid. A standard 5 Hz transformer can accomplish this separation.

53.5 % Photodiode RF Power Conversion Efficiency
Optical Fiber Communication Conference, 2010A record 53.5% RF power conversion efficiency is reported for a photodiode delivering 24.4 dBm output power. This is achieved by optimized photodiode design, optical intensity-envelope shaping with a Mach-Zehnder modulator and photodiode signal compression.

Efficiency of Traction Power Conversion Based on Crosswind Motion
2013This review paper is devoted to analytical modeling of the so-called kite wind generator (KWG) whose power conversion operation uses a tethered kite to mechanically drive a groundbased electric generator. An important aspect of the KWG operating principle is the controlled crosswind motion of the kite, which is used to increase the kite traction force.

Compact and efficient transformerless power conversion system
Proceedings of 1996 International Power Modulator Symposium, 2002The DC Transformation Inc. (DCT) transformerless Power Conversion System (PCS) is a new technology that efficiently steps-up and steps-down DC at high power and high voltage levels. The transformation is accomplished through the use of low cost solid state switching devices, capacitors, air-core inductors and an intelligent control system.

Effects of DSSC configuration on power conversion efficiency
2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014The purpose of this paper is to outline the effects of dye-sensitised solar cell (DSSC) configuration on useable output power provided through low-power, step-up DC-DC converters. It is shown that by connecting DSSCs in series rather than in parallel, higher power conversion efficiency is achieved due to increased cell voltage, and this in turn results

Routes to high efficiency photovoltaic power conversion
2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013The thermodynamic efficiency limit for solar power conversion sits at 87% yet the majority of photovoltaic devices operate at efficiencies of 20% or less. Multi-junction solar cells presently represent the most accessible technological route to high efficiency and are now operating close to the radiative limit, where optical coupling between sub-cells ...

Monostable circuits with maximum power-conversion efficiency
International Journal of Electronics, 1974A monostable multivibrator using a complementary pair of transistors which needs no standing power is described. At the output terminals rectangular pulses having rise and fall times in the nanosecond range are obtained. The duration of output pulses is controlled by a diode clamp and can be made almost independent of the d.c.
