NOVELTY - The electric power supply system has output voltage, yielded by a series connection of the output capacitors (2c) at the output of an intermediate section (3), which is equal to the product of input voltage and the number of contact member (3b,3c) pairs in the intermediate section with complete isolation between an input battery (1) and load (L). A recycling circuit is connected to intermediate section so that recycling circuit supplies power to recharge the depleted input voltage source whenever the input battery or input capacitors are isolated from the transit capacitors.    USE - Electric power supply system for electric power generating system. Can also be used for vehicle system (claimed) utilized by electric vehicles.    ADVANTAGE - Enhances the distance range, via a comparatively simpler construction, to achieve the required output voltage with minimum number of batteries for desired speed of the vehicle and maintain ampere-hour rating of the batteries and enables uniform operation recharging system or recharging circuit with complete isolation of the battery recharging system from the drive load of the vehicle since the recycling circuit is connected to intermediate section so that recycling circuit supplies power to recharge the depleted input voltage source whenever the input battery or input capacitors are isolated from the transit capacitors. Prevents the battery from depleting faster since the condensers receive the floating voltage that is available after the full charging of the battery by the wind generator units. Reduces the overall weight of the vehicle which indirectly leads to energy saving and improved mileage since the weight of the battery and the space occupied by the battery is lowered.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) an intermediate device; and    (2) a method of working of a power supply system with a power supply unit.
