Abstract: 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 ? 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.
Abstract: The invention relates to inertial systems for the accumulation and conversion of energy, and can be used as a power unit to drive various machines and vehicles. According to the disclosed method, a source of mechanical oscillations is used to generate an alternating rotational torque which is applied to the working train made capable of unidirectional rotational motion. An inertial vibrator disposed axially on the working train is used as the oscillation source.
