description Described embodiments include a rectifier circuit comprising a first resistor with first and second resistor terminals, and a second resistor with third and fourth resistor terminals. The first and third resistor terminals are coupled to an auxiliary power terminal. A current source is coupled between the second resistor terminal and a ground terminal. An amplifier has a first amplifier input coupled to the second resistor terminal, and a second amplifier input coupled to the fourth resistor terminal. A first transistor is coupled between the fourth resistor terminal and a damping terminal, and has a first control terminal coupled to the first amplifier output. A gate drive circuit has an input coupled to the damping terminal. A second transistor is coupled between the damping terminal and a bootstrap supply terminal, and has a second control terminal coupled to an output of the gate drive circuit.
