Abstract

See full text

A rectification circuit connected to a coil and a capacitor, includes, on each terminal side of the coil, a high-side transistor connected between a terminal of the coil and the capacitor, first and second low-side transistors connected in parallel between the terminal of the coil and a fixed potential, a comparator that causes the first low-side transistor to be turned on when a voltage of the terminal of the coil decreases to a first value and then turned off when the voltage increases to a second value that is higher than the first value and lower than the fixed potential, and a controller that causes the second low-side transistor to be turned off when the voltage decreases to a third value that is higher than the second value and lower than the fixed potential, and then turned off when the voltage increases to the third value.
