Abstract:
A controller for use in a power converter of a motor drive includes a control circuit configured to turn ON a high side switch by sinking a current of an ON signal. A high side signal interface circuit is coupled to receive the ON signal to generate a drive signal to control switching of the high side switch in a presence of a common mode signal caused by slewing at a half bridge node. The high side signal interface circuit includes a common mode cancellation circuit coupled to provide a common rejection signal to provide a cancellation or rejection of the common mode signal. A first current hysteresis comparator is coupled to receive a common mode rejection signal, a first current signal, and a fourth current signal, and generate a first output signal in a presence of a common mode voltage.

Claim (Index 9):
A resonant power converter, comprising:\n a high side switch coupled to receive an input voltage at one end of the high side switch; a low side switch coupled to an input return at one end of the low side switch, wherein an other end of the low side switch is coupled to an other end of the high side switch at a half bridge node, wherein a voltage of the half bridge node resonates between a ground reference and the input voltage; a tank circuit coupled to the high side switch and the low side switch at the half bridge node; an energy transfer element coupled to the tank circuit to transfer energy from an input of the resonant power converter to an output of the resonant power converter in response to switching of the high side switch and the low side switch; and a controller coupled to control switching of the high side switch and the low side switch in response to a feedback signal representative of the output of the resonant power converter, wherein the controller includes:\n a control circuit configured to turn ON the high side switch by sinking a current of the ON signal; and \n a high side signal interface circuit coupled to receive the ON signal to generate a drive signal to control switching of a high side switch coupled to a half bridge node of the power converter in the presence of a common mode signal caused by slewing at the half bridge node, wherein the high side signal interface circuit comprises:\n a common mode cancellation circuit coupled to provide a common mode rejection signal to provide a cancellation or rejection of the common mode signal, wherein the common mode cancellation circuit generates a first current signal and a fourth current signal; and \n a first current hysteresis comparator coupled to receive the common mode rejection signal, the first current signal, and the fourth current signal, and generate a first output signal in the presence of a common mode voltage.
