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 power switch including a drain terminal, a source terminal, and a gate terminal; and
one or more controllers configured to detect a voltage from the gate terminal to the source terminal of the power switch as a gate-to-source voltage, and control a gate control signal to the gate terminal based on the detected gate-to-source voltage, wherein the one or more controllers include:
a high-speed gate-to-source voltage detector connected to the gate terminal and the source terminal of the power switch, the high-speed gate-to-source voltage detector configured to detect the gate-to-source voltage of the power switch.
 
9. A system including:
a power module for an inverter for an electric vehicle, the power module comprising:
a drain connection;
a source connection;
a power switch including a drain terminal, a source terminal, and a gate terminal, the power switch configured to control a flow of current between the drain connection and the source connection; and
one or more point-of-use controllers configured to detect a gate-to-source voltage between the gate terminal and the source terminal of the power switch, and control a gate control signal to the gate terminal based on the detected gate-to-source voltage, wherein the one or more point-of-use controllers includes:
a high-speed gate-to-source voltage detector connected to the gate terminal and the source terminal of the power switch, the high-speed gate-to-source voltage detector configured to detect the gate-to-source voltage of the power switch.
 
13. A system comprising:
one or more point-of-use controllers for a power module for an inverter, the one or more point-of-use controllers configured to:
receive a gate command;
receive a gate voltage signal from a power switch;
receive a source voltage signal from the power switch;
detect a gate-to-source voltage based on the received gate voltage signal and the received source voltage signal; and
generate a gate control signal for a gate terminal of a power switch, based on the received gate command and the gate-to-source voltage.
