  • MITIGATION OF MICROCONTROLLER RESTART FROM POST-FAILURE SHUTDOWN CONDITION
    Publication number: 20220021199
    Abstract: Improvements to a power input circuit of an electric motor drive system are provided. The power input circuit is provided between a power source (e.g., battery), and a load (e.g., an inverter and a motor in the electric motor drive system). The power input circuit can comprise controllable switches for reverse polarity protection and isolation of the inverter under supply short circuit condition. In addition, an improvement to a power input circuit can comprise connection of a power supply (e.g., voltage regulator) to the external power source input side of a reverse polarity protection circuit in the power input circuit to mitigate against microcontroller restart from post-failure shutdown condition. Connection of a low-power diode in series with the voltage regulator also provides for reverse polarity protection.
