Mobile radio apparatus with voltage supply source

摘要

The apparatus includes several voltage sources (1-6) which are connected in series and which are coupled to a changeover switch (9,12) for switching between different partial sections (1-3 or 4-6) of the series-connection to obtain a component voltage. The changeover switch is regulated by a control (12), to provide a changeover in time intervals such that the voltage sources have the same performance in time average. Preferably the changeover switch is controlled to form the component sections. Typically the control contains a microprocessor for transmitting control signals for the switch. The partial sections may deviate from allocated consumer appliance voltage by the value of one voltage source.
