摘要：A power supply control system which prevents thermal overload of the apparatus to which power is being supplied. The supply voltage is controlled so that as the temperature of the apparatus increases beyond a predetermined threshold the supply voltage is reduced in incremental steps, thereby reducing thermal dissipation.
