摘要： A circuit arrangement is for operating a load having a reactive characteristic on an AC power supply. The circuit arrangement enables the best possible reactive power compensation, that is, enables operation close to a cos θ of 1, in order to increase the overall efficiency of the arrangement or to achieve optimal energy savings. In order to control critical operating states, a feedback loop is provided that supplies a control current to a further reactive circuit element. This further circuit element is arranged parallel to the load or to the power factor correction capacitor, and is acted upon by a control current such that the control current counteracts a change in the reactive component of the load. The control current is derived from the load current as a variable proportional to the load current. In this way, a reactor for optimizing electromagnetic consumption is created.
