SYSTEM FOR PWM CONTROLLING A BIDIRECTIONAL DC/DC CONVERTER, CAPABLE OF CONTROLLING FIRST AND SECOND SWITCH THROUGH A DEC CONTROLLER

摘要

PURPOSE: A system for PWM controlling a bidirectional DC/DC converter is provided to reduce an error by being connected to first and second switch and transferring a PWM duty ratio control signal.;CONSTITUTION: In a system for PWM controlling a bidirectional DC/DC converter, a bidirectional buck-boost converter(100) comprises a power supply circuit portion and a filter section. The output ripple of the bidirectional buck-boost converter is less than 2%. A power circuit unit is comprised of first and second switch and is connected to a battery power. A filter is comprised of an inductor(L) and an output filter capacitor(C). A DEC controller(200) is connected to first and second switch and transfers a PWM duty ratio control signal.;COPYRIGHT KIPO 2012
