BIDIRECTIONAL DC/DC CONVERTER SYSTEM USING INTERLEAVE METHOD AND DRIVING METHOD THEREOF

摘要

PURPOSE: A two-way DC/DC converter system, which is driven by an interleaved mode, and an operating method thereof are provided to use a convertible interleaved mode to control a configured converter so that output terminal filters are to be reduced in number or to be omitted by reducing input/output components, and to use leakage reactance of a transformer and a half bridge type snubber capacitor so that a resonant circuit is configured for a zero current control; thereby miniaturizing and weight-lightening the system. CONSTITUTION: A two-way DC/DC converter system comprises a first converter(110) which includes a first input module with a first high frequency transformer, and a first output module which is connected through the first high frequency transformer to the first input module; a second converter(120), which includes a second input module, is connected to a battery, and comprises a second high frequency transformer and a second output module which is connected through the second high frequency transformer to the second input module; the battery(Vin) which is connected in parallel to one side of the first converter and the second converter; and a load(R) which is respectively connected to the first converter and the second converter; and an interleaved switch control circuit(130) that controls the turn-on/turn-off of switching elements which are included in the first and the second converter in order to use the interleaved mode to drive the first and the second converter.
