  • Patent number: 10948541
    Abstract: A system for diagnosing switching element selectively connecting Y-capacitors to ground is provided. The state of a switching device in a power conversion circuit is adjusted such that voltages of different levels are applied to the Y-capacitors, respectively. Therefore, a Y-capacitor disconnect switch which connects a plurality of Y-capacitors connected in common to a DC link to chassis ground is diagnosed.
