Electrodynamic tethers are proposed as propulsion and energy harvesters for space probes orbiting planets with a magnetic field and ionosphere, however there are no descriptions in the technical literature of the design of an electrical power system for such an application at subsystem and circuit detail. This paper presents a proposal for such a p...

A simple multiplier for the estimation of the power yield of a solar panel may be realized with a pulse-width-modulator working as analog multiplier circuit. Though the output of the pulse width modulator multiplication is not proportional to the output power of the solar panel, it will be shown that its maximum follows the maximum of the power cur...

A simple analog multiplier for the estimation of the power yield of a solar panel may be realized with a pulse width modulator working as analog multiplier circuit of the current yield and the duty cycle of the converter used to condition the panel. Though the output of the pulse width modulator multiplication is not exactly proportional to the out...
