1. A switch control system, comprising:
a voltage source configured to output a source voltage on a voltage line;
a first gate driver connected to a gate control signal line to receive a gate control signal from a controller, wherein the first gate driver is connected to the voltage line to receive the source voltage, wherein the first gate driver is connected to a first terminal line to output a first gate voltage signal to a first terminal of a switch;
an inverter connected to the gate control signal line and configured to receive the gate control signal and output an inverted gate control signal; and
a second gate driver connected to the inverter to receive the inverted gate control signal from the inverter, wherein the second gate driver is connected to the voltage line to receive the source voltage, wherein the second gate driver is connected to a second terminal line to output a second gate voltage signal to a second terminal of the switch;
wherein:
the first gate driver and the second gate driver are integrated in a single integrated circuit such that the switch control system includes a single voltage line to the single integrated circuit and a single ground line from the integrated circuit; or
the first gate driver and the second gate driver are hosted on separate integrated circuits such that the switch control system includes two voltage line branches and two ground line branches.
