Title:
POWER CONVERT EQUIPMENT
Document Type and Number:
Japanese Patent JP2022112366
Kind Code:
A
Abstract:
To provide power convert equipment having reduced common mode noise while reducing the space allocated for noise suppression components.SOLUTION: A convert section (10) adjusts the voltage of DC power supplied from a DC power source (2) and outputs it. An inverter section (20) converts the DC power output from the convert section (10) into AC power. A board-mounted common mode choke coil (Lc) is connected to the wiring to which a switching element (Q11) in the convert section (10) is connected and the wiring to which switching elements (Q21-Q24) in the inverter section (20) are connected. The common mode choke coil (Lc) has broadband impedance characteristics corresponding to noise in multiple target bandwidths generated by the switching elements (Q11, Q21-Q24).SELECTED DRAWING: Figure 3
