Abstract
Disclosed herein is a converter including a switching unit, an energy storage unit for storing energy from a direct current (DC) input voltage and then generating an output voltage according to a switching operation of the switching unit, and a switching controller for controlling the switching unit to selectively execute a first operation mode for turning on the switching unit at a fixed frequency or a second operation mode for turning on the switching unit when a voltage between one end and the other end of the switching unit reaches a zero point of a resonance waveform, wherein the switching controller includes an operation mode selection unit for selectively executing the first operation mode or the second operation mode according to whether the voltage between one end and the other end of the switching unit resonates.
