<p>PURPOSE:To make it possible to feed various DC voltages from a miniature and lightweight DC-DC converter by inserting a flywheel diode in parallel to the input of a voltage-dividing power supply. CONSTITUTION:Power from main power supply 11 is fed to electronic loads 141 to 14n of the switchboard via voltage-diviging power supplies 301 to 30n. By inserting flywheel diodes 31 in parallel to inputs of respective voltage-dividing power supplies, impedance values between input sides and electronic-system load sides are made low sufficiently to remove variations in potential, and the input and output of the DC-DC converter are connected together directly. Consequently, a miniature and light-weight DC-DC converter can be obtained.</p> |
