QUASI-CURRENT-MODE HYSTERESIS CONTROL METHOD, QUASI INDUCTOR CURRENT EMULATOR OF SWITCHING DC-DC CONVERTER, AND HYSTERETIC SWITCHING DC-DC CONVERTER

摘要

The present invention relates to a quasi-current-mode hysteresis control method, a quasi inductor current emulator of a switching DC-DC converter, and a hysteretic switching DC-DC converter. Provided is a hysteretic switching DC-DC converter using a quasi-current-mode hysteresis control method, in which a sensing voltage of the quasi inductor current emulator is initialized when a feedback output voltage input in a hysteretic comparator is in contact with a boundary voltage of a hysteresis window. According to the present invention, an output voltage (V_O) is recovered quickly in a transient response.;COPYRIGHT KIPO 2017
