Document Type and Number:
Japanese Patent JPWO2022124395
Kind Code:
A1
Abstract:
A power converter apparatus includes: a pair of input terminals and a pair of output terminals; a first series circuit including a first inductor and a first switch element and being connected in parallel to the pair of input terminals; a switching circuit that switches, by using a second switch element, a voltage between both ends of the first switch element; a power converter circuit that converts an input voltage inputted to the pair of input terminals to a predetermined output voltage and then outputs the output voltage to the pair of output terminals; and a ripple cancellation current generator circuit that, in case of the first switch element being turned on and off, generates a ripple cancellation current for cancelling a ripple current generated by accumulation and discharge of current energy to and from the first inductor.
