Abstract
This article presents a three-switch (3S) boost con-
verter with hysteresis current control applied in MiniLED panels.
It uses only three power switches to achieve high conversion ratio
(=7.5) and low inductor current (20% lower than conventional
boost converters). Meanwhile, the charging time of the flying
capacitor will increase as the duty cycle increases. It enables
the proposed 3S boost converter to have a high drive current
(=1.2 A). In addition, the right half-plane (RHP) zero of
the propo
