  • A complex network approach for identifying vulnerabilities of the medium and low voltage grid

    The vision behind the smart grid promises, among other things, to bring more attention to the lower layers of the distribution network where users are gradually transforming into prosumers. Independent of this transformation, users will expect the same (or higher) level of reliability of the infrastructure. In this paper, we consider physical samples from the Dutch medium and low voltage network ...

  • How to clean solar lights

    Summer's over and now is the ideal time for a hefty portion of us here in the United States to consider fall cleanup. In the event that you have solar powered lighting, or any scene lights besides, it’s not difficult to harm or even demolish lights once rakes and leaf blowers turn out. Fortunately, there are some simple and fast ...

  • A fast–response sliding–mode controller for quadratic buck converter

    The switched–mode power supplies are widely used in very low voltage and high–power applications where large conversion ratios are required. In such cases, the quadratic buck converter is the suitable one compared to buck, cascaded buck and multi–phase choppers, because of their limitations in switching frequency and losses. This paper presents mathematical analysis, design and simulation of a ...

  • Improvement of perturb and observe MPPT method for photovoltaic systems: case of study

    Maximum power point tracking system is widely used to maximise output power of photovoltaic array. A crucial issue of this system is an algorithm of maximum power point seeking. Well–known perturb and observe technique is optimal solution in terms of the ratio of cost and efficiency. However, this algorithm has some disadvantages such as oscillation around a maximum power point and decrease in ...

    First, the difference between the high frequency and power frequency Workers Electric Reach Truck charger power devices operating in the linear state, which means he used up the power device is always at work, and therefore would result in low efficiency of his work, generally in the range of 50% to 60%, have to say he is good linear ...

  • Modelling, design and control of a SEPIC power factor corrector for single–phase rectifiers: experimental validation

    In this paper, a new general case switching–function–based model is proposed for a DC–to–DC single ended primary inductance converter (SEPIC). Compared to conventional buck or boost converters, this topology allows a low current ripple at the input for a relatively low level of the DC–bus voltage. The converter is used as a power factor correction (PFC) circuit for a single–phase rectifier and, ...

  • A power-flow control method for hybrid active front-end converters

    The hybrid active front-end converter, which is composed of a capacitor and a voltage source converter in series connection, has been presented recently. Compared with grid-connected converter, the hybrid converter could be operated with reduced dc voltage as well as small-sized passive filters due to series-connected capacitor. This paper presents a power flow control method for a hybrid active ...

  • Switched-coupled-inductor DC/DC converters with high voltage conversion ratio

    When a low voltage DC power source is used, a DC-DC converter with a high step-up voltage gain is required to raise the voltage to more applicable levels. This is typically achieved by using classical converters driven by pulse width modulation (PWM) waves with extremely high duty cycles. Although theoretically step-up converters can achieve an infinite gain as the duty cycle approaches unity, in ...
