Patent ID: 11942900
Assignee: POWER INTEGRATIONS, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A controller for use in a power converter, comprising:
a driver modulator configured to generate a drive signal in response to a control signal to control switching of a power switch of the power converter to regulate transfer of energy from an input of the power converter to an output of the power converter; and
a compensated amplifier configured to generate the control signal in response to a reference signal and a sensed signal representative of the output of the power converter, wherein the compensated amplifier comprises:
a first amplifier coupled to receive the sensed signal and the reference signal and configured to generate a first error signal in response to the sensed signal and the reference signal;
a second amplifier coupled to the first amplifier and configured to generate a second error signal in response to the sensed signal and the reference signal;
an integrator coupled to the first amplifier and configured to generate an integrated error signal in response to the first error signal; and
an arithmetic operator coupled to the second amplifier and configured to generate a control signal in response to the integrated error signal and the second error signal.
