Title: Dc/dc converter
Inventor: TAKEGAMI EIJI
IPC: H02M3/28
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To suppress increase in the reset voltage of a transformer effectively, during off interval of a switching element through a simple circuit configuration. SOLUTION: When the voltage across the switching element 2 reaches the operating voltage of a Zener diode 21 during off interval of the switching element 2, the Zener diode 21 conducts, to prevent the reset voltage from increasing furthermore. The voltage across the switching element 2 is thereby clamped at the operating voltage of the Zener diode 21, even if the one interval of the switching element 2 is widened. Consequently, increase in the reset voltage of the transformer 1 can be suppressed effectively during off interval of the switching element 2, through a simple arrangement where the Zener diode 21 is added to existing circuit configuration.
