ZCS DC-DC CONVERTER

摘要

PURPOSE: A zero current switching type DC/DC converter is provided to reduce a switching loss by using a zero current switching method. CONSTITUTION: A zero current switching type DC/DC converter comprises a DC voltage input unit, a high frequency transforming unit(200), and a DC voltage output unit. The DC voltage input unit comprises a voltage source(114) and a switch element. The DC voltage input unit comprises resistance(124) and a second capacitor(122) respectively serially connected to the voltage source and a coil. A third capacity(112) is connected in parallel with the voltage source. The high frequency transforming unit comprises the coil, a first capacitor(134) LC resonating a leakage inductance component of the coil.
