Abstract:
The invention relates to a photovoltaic system for generating an output voltage which is essentially uninfluenced by varying irradiation, the photovoltaic system comprising a photovoltaic source (1) having an input terminal (2) and an output terminal (3). The photovoltaic system is characterized in that the photovoltaic system comprises a voltage adding arrangement (4) comprising a first input terminal (5) and an output terminal (6), the voltage adding arrangement (4) is connected in series with the photovoltaic source (1), and in that a first route (7) comprising a voltage source (9) and a second route (8) constituting a voltage source bypass extend between said first input terminal (5) and said output terminal (6) of the voltage adding arrangement (4), said first and second routes being alternately activateable.

Abstract:
An apparatus for controlling a thyristor controlled series capacitor connected to a power transmission line. A thyristor firing control includes a unit for effectuating a desired capacitor voltage zero crossing in dependence of a line current and a capacitor voltage in response to a command signal. A command control provides the command signal to the thyristor firing control. The command control includes a damping control including a damper configured to damp at a least one discrete frequency.
