Classification: CPC H | IPC H

Claim 9:
10. A control system, comprising:
a high-side switch and a low-side switch that drive a load;
a controller that outputs a first PWM signal for controlling the high-side switch and a second PWM signal for controlling the low-side switch; and
a gate driver that drives the high-side switch and the low-side switch based on the first PWM signal and the second PWM signal,
wherein the gate driver includes:
a galvanic isolator;
a transmitting circuit that transmits a transmission signal via the galvanic isolator;
a receiving circuit that receives a received signal corresponding to the transmission signal via the galvanic isolator;
an encoding circuit that encodes the first PWM signal and the second PWM signal to generate the transmission signal;
a decoding circuit that decodes the first PWM signal and the second PWM signal from the received signal;
a first driver circuit that drives the high-side switch based on the decoded first PWM signal; and
a second driver circuit that drives the low-side switch based on the decoded second PWM signal.
