ABSTRACT:
A charging system is provided with a device and a first energy source remotely located from each other. The device has a second energy source to be charged and that receives energy from a power supply of the first energy source. The device further has a measuring circuit. The measuring circuit provides an error signal obtained from an electrical quantity of the second energy source. The first energy source also has a regulation circuit coupled to the power supply. A high impedance control input of the regulation circuit receives the error signal. In response to this error signal, the regulation circuit regulates the voltage of the power supply.
