| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This report presents a novel inverter circuit structure for suppressing common-mode (CM) current on output cable. Adding impedance elements between the output trace of each phase and the bus traces, CM voltage propagation from a certain leg to own-phase output terminal can be described with a bridge-shaped equivalent circuit. Furthermore, connecting output traces mutually with additional impedance elements, CM voltage propagation from a certain leg to other-phase output terminals can also be described with another bridge circuit. Applying impedance balance method, we can suppress noise propagation from each leg to all output terminals simultaneously when both bridge circuits are balanced. We derived the balance condition for the single-phase inverter, and verified that CM voltage transfer ratio can be suppressed. Finally, it was confirmed that CM current decreased by over 20 dB using circuit simulation of the three-phase inverter. | |
