    Abstract: A front stage circuit of a transformer includes a switch series unit, capacitors, and a ground electrical path. The switch series unit, connected in parallel to a power supply, includes odd-numbered/even-numbered switches configured to be alternately turned ON. Assuming that mutual connection points of the switches and points at both ends of the switch series unit are m nodes in total, and one of the points at the both ends is a ground node, the capacitors are provided on at least one of a first electrical path that combines odd nodes and leads them to a first output port, and a second electrical path that combines even nodes and leads them to a second output port, and the capacitors are present to correspond to (m?1) nodes excluding the ground node. The ground electrical path connects the ground node directly to the first output port without an interposed capacitor.
