Control circuitry for power semiconductor switches using control signal feedback

An apparatus comprising:

• a first power semiconductor switch;
• a second power semiconductor switch coupled in series or in parallel with the first semiconductor switch;
• a first driver circuit configured to drive a control terminal of the first power semiconductor switch responsive to a first control signal;
• a second driver circuit configured to drive a control terminal of the second power semiconductor switch responsive to a second control signal;
• a first control circuit configured to generate the first control signal responsive to a drive signal that commands transitions of the first and second semiconductor switches between off and on states in unison, the first control circuit generating the first control signal according to a comparison of a voltage at the control terminal of the first semiconductor switch to a first reference voltage that varies for transitions of the first semiconductor switch between the off and on states in a manner defined by a first predetermined profile to provide a desired dynamic behavior for the voltage at the control terminal of the first semiconductor switch for the transitions of the first semiconductor switch between the off and on states;
• and
• a second control circuit configured to generate the second control signal responsive to the drive signal, the second control circuit generating the second control signal according to a comparison of a voltage at the control terminal of the second semiconductor switch to a second reference voltage that varies for transitions of the second semiconductor switch between the off and on states in a manner defined by a second predetermined profile to provide a desired dynamic behavior for the voltage at the control terminal of the second semiconductor switch for the transitions of the second semiconductor switch between the off and on states.
