OUTPUT VOLTAGE CONTROLLER OF SOLAR BATTERY

PURPOSE:To simplify the constitution of a control circuit, by short-circuiting solar batteries properly and controlling their output voltage. CONSTITUTION:Four solar batteries SB2-SB5 of the solar batteries are fitted with a slide switch SW. Namely, this slide switch has four stages SW1-SW4; when the switch is slid by one stage, the contact SW1 is closed to form a short circuit across the solar battery SB5 and when it is slid by two stages, the contacts SW1 and SW2 are closed to form short circuits across the solar batteries SB5 and SB4 respectively. Similarly, when it is slid by four stages, short circuits across the SB2-SB5 are formed and only the output voltage of the solar battery SB1 is supplied to a CPU.
