Abstract:
1. A driver for a switch, the driver comprising: a primary side having a trigger input and a pulse width modulation (PWM) signal input; a secondary side comprising an analog-to-digital converter (ADC), wherein the primary side and the secondary side are configured to be separated by a galvanic isolation barrier; a first communication channel and a second communication channel, wherein the primary side and the secondary side communicate over the galvanic isolation barrier via the first and the second communication channels; wherein the primary side is configured to receive a trigger signal at the trigger input and forward the trigger signal to the ADC of the secondary side of the driver via the first communication channel; wherein the primary side is configured to receive a PWM signal at the PWM signal input and forward the PWM signal to the ADC of the secondary side of the driver via the second communication channel; wherein the secondary side comprises a multiplexer configured to output a delayed signal of the PWM signal or the trigger signal to the ADC; and wherein the ADC is configured to start a measurement upon receiving the trigger signal.
