Zusammenfassung:	A MICROCOMPUTER (1) OUTPUTS A COMMAND TO A CONTROL IC (2) TO OPERATE FIRST AND SECOND LOADS (6, 9).THE CONTROL IC (2) SETS FIRST AND SECOND DC/DC CONVERTERS (4, 7) ON-STATE TO OPERATE THE FIRST AND SECOND LOADS (6, 9). THE FIRST DC/DC CONVERTER (4) CONVERTS A VOLTAGE OF POWER SUPPLIED FROM A POWER SUPPLY (3) FROM 8.4V TO 1.5V, AND SUPPLIES IT TO A CONSTANT CURRENT CIRCUIT (5). THE CONSTANT CURRENT CIRCUIT (5) CALCULATES A CURRENT VALUE OF A LOAD CURRENT TO BE CONSUMED IN THE FIRST LOAD (6) AND THE SECOND LOAD (9) TO WHICH POWER IS SUPPLIED VIA THE SECOND DC/DC CONVERTER (7), AND COMPARES IT WITH AN ELECTRICAL CURRENT VALUE AT WHICH THE UTMOST CONVERSION EFFICIENCY IS ACHIEVABLE IN THE FIRST DC/DC CONVERTER (4). IF THE LOAD CURRENT IS SMALLER THAN THAT, THE CONSTANT CURRENT CIRCUIT SUPPLIES A SURPLUS POWER TO A CHARGING BATTERY (8), AND IF THE LOAD CURRENT IS GREATER THAN THAT, IT RECEIVES A DEFICIENT POWER FROM THE CHARGING BATTERY (8).
