  • Instantaneous voltage measurement technique for PWM voltage source inverters

    The pulse width modulated (PWM) voltage source inverter (VSI) is almost universally used in industrial motor drives. Although measurement of the VSI output voltage is required in many applications, accurate measurement is problematic due to the high frequency inverter switching. Many commonly used inverter output voltage measurement methods, such as indirect and direct voltage measurement, ...

  • Fuel Cell Voltage Monitoring Considerations

    Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There ...

  • Development of modulation strategies for three-phase to two-phase matrix converters

    In this paper, the modulation strategy is developed for three-phase to two-phase matrix converters for synthesising balanced and unbalanced output voltages from balanced and unbalanced input voltages. Reduction of low order input current harmonics with sinusoidal output voltages is achieved by using the proposed switching strategies. The other advantage of the proposed method is the significant ...

  • Regenerative snubber for UPS inverter

    An uninterrupted power supply (UPS) is used to provide electrical power to a load during an emergency situation in which the main utility power is not available. UPS topologies are well known. The inverter plays the most important role as an element in the UPS system. Usually, pulse width modulated inverters with voltage control and waveform shaping are used in UPS. This paper proposes an ...

  • A new fault detection, classification and location scheme for transmission line

    Using the powerful analysing and decomposing features of wavelet transform, a new fault detection scheme is presented. Further, the same technique has been extended for fault classification and accurate fault location from the relaying point to the fault using a radial basis function neural network (RBFNN) which provides a more efficient approach for training and computation. The relaying scheme ...

  • Spi-Sun simulator sets the standard

    Solar Simulators are critical to the industry testing photovoltaic modules featuring light sources that closely match the solar spectrum. Spire’s simulators can test the full range of solar modules – including crystalline or thin film. The importance of solar simulation is clear – solar modules must be tested under a standard set of conditions to assure consistency of results. ...

  • Solving solar-power issues

    Certainly, no one would accept only having electricity during the day, and then only on clear days, if they have a choice. We need energy storage -- batteries. Unfortunately, batteries add a lot of cost and maintenance to the PV system. Currently, however, it's a necessity if you want to be completely independent. One way around the problem is to connect your house to the utility grid, buying ...


  • Solar power generation by photovoltaic technology

    The various forms of solar energy, solar heat, solar photovoltaic, solar thermal electricity, and solar fuels offer a clean, climate-friendly, very abundant and in-exhaustive energy resource to mankind. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been under way since the ...

  • Rotork valve automation at solar power plants - Case Study

    Overview Spain is now the world's largest generator of electricity from solar power plants. Spanish solar energy plants utilise parabolic trough technology combined with a thermal storage system using molten salt batteries to maximise their power generating capacity. The parabolic trough is constructed as a long parabolic mirror with a Dewar tube running its length at the focal point. ...
