Claim of US Patent No. 10,973,090

1. An induction heating power supply apparatus comprising:a smoothing section configured to smooth a pulsating current of DC power output from a DC power supply section; and
an inverter configured to convert the DC power smoothed by the smoothing section to AC power,
wherein the inverter includes a first bridge and a second bridge that are connected in parallel with each other,
wherein the smoothing section comprises a pair of bus bars connected to the inverter, at least one capacitor connected to the pair of bus bars, and at least one connection member,
wherein the at least one capacitor includes a first capacitor and a second capacitor and the at least one connection member includes a first connection member and a second connection member,
wherein each of the bus bars comprises an external surface extending in a current flow direction, the external surface including at least one flat face having a larger surface dimension than another face of the external surface in a direction perpendicular to the current flow direction,
wherein the pair of bus bars are arranged in a layered manner such that the flat faces of the pair of bus bars are opposed to each other and such that an insulator is sandwiched between the flat faces the pair of bus bars,
wherein the pair of bus bars are connected to the inverter through the first connection member and the second connection member, and
wherein the first capacitor is connected to the first bridge of the inverter through the pair of bus bars and the first connection member, and the second capacitor is connected to the second bridge of the inverter through the pair of bus bars and the second connection member.
