Zusammenfassung:	A device and method of controlling charge pump are provided. The device of controlling charge pump includes: a charge pump circuit connected to an input circuit; a first capacitor coupled to the charge pump circuit and provided as an element of a resonant circuit; a first switching element connected to the first capacitor; and a controller configured to read an input current and/or an input voltage from the input circuit, generate a pulse width modulation signal according to the input current and/or the input voltage, and output the pulse width modulation signal to control the first switching element. Therefore, THD and harmonic can be improved while the cost of the circuit is decreased.
