1. A system comprising:
an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes:
a first galvanic isolator separating a low voltage area from a high voltage area, the first galvanic isolator having a first galvanic isolator output path;
a second galvanic isolator separating the low voltage area from the high voltage area, the second galvanic isolator having a second galvanic isolator output path;
an amplifier in the high voltage area, connected to the first galvanic isolator via the first galvanic isolator output path, and connected to the second galvanic isolator via the second galvanic isolator output path, the amplifier having a first amplifier output path and a second amplifier output path;
a comparator in the high voltage area, and connected to the amplifier via the first amplifier output path and the second amplifier output path, the comparator having a first comparator output path and a second comparator output path; and
a pulse reshape and envelope detector in the high voltage area, and connected to the comparator via the first comparator output path and the second comparator output path.
