Abstract
A DC-DC converter apparatus includes a main converter section, a main control section, a supplemental power supply section, a signal processing section and a supplemental control section. The main converter section converts a D.C. input into an adequate D.C. output and supplies the converted D.C. output to a load. The supplemental power supply section supplies operating electric power to the main converter section and main control section of the DC-DC converter apparatus. The supplemental control section controls the operative or non-operative state of the supplemental power supply section based on a signal from the signal processing section. The main control section controls the operative or non-operative state of the main converter section in response to the operation of the supplemental power supply section.
