Abstract: A system includes a control board comprising: a microprocessor configured to output a PWM signal; a primary shutoff path circuit, an upper MOSFET shutoff circuit, and a lower MOSFET shutoff circuit, each of the circuits configured to receive the PWM signal; a first buffer provided at an output of the primary shutoff path circuit; a second buffer provided at an output of the upper MOSFET shutoff circuit; a third buffer provided at an output of the lower MOSFET shutoff circuit; a first resistor and a second resistor provided in parallel at the first buffer and configured to provide a first feedback signal; a third resistor and a fourth resistor provided in parallel at the second buffer and configured to provide a second feedback signal; and a fifth resistor and a sixth resistor provided in parallel at the third buffer and configured to provide a third feedback signal.
