A method for controlling and enhancing a startup operation for a combined cycle power block (block) having at least one gas turbine and at least one steam turbine, wherein operating parameters define performance and operational characteristics for the startup operation, the method comprising: receiving measured operating parameters from a plurality of reference blocks and, for each of the plurality of reference blocks, a plurality of types of the startup operations; given the measured operating parameters, developing one or more reference transfer functions between two of the measured operating parameters; receiving measured operating parameters from the startup operation of a target block; given the measured operating parameters from the target block, developing one or more transfer functions for the target block between two of the operating parameters; selecting one of the reference transfer functions; and normalizing the transfer function of the target block per the selected reference transfer function.

Power management integrated circuits (PMICs) and related methods. In one aspect a PMIC which is operable to provide a plurality of PMIC power states is arranged to provide a predetermined delay before a power state transition. The delay is applied after receipt by the PMIC control circuitry of a power state transition command. Applying a delay allows time for the system powered by the PMIC to perform any necessary shut-down procedures and terminate active processes before power is removed, preventing corruption of the system. The delay is preferably configurable. The PMIC may also be arranged to control power converters which are external to the PMIC. In another aspect the PMIC has translation circuitry for providing the control settings of one power block, e.g. power converter, with any necessary modifications to be used by another power block. This means that only one set of control settings needs to be updated to change the output of both power blocks simultaneously.

A multi-phase power block for a switching regulator includes a phase control circuit, N power cells and a current sharing control circuit. The phase control circuit is configured to receive a single phase PWM clock signal and generate N clock signals in N phases. Each of the N power cells includes a pair of power switches, gate drivers, a control circuit receiving one of the N clock signals and generating gate drive signals for the gate drivers, and an inductor. The current sharing control circuit is configured to assess the inductor current at the inductor of the N power cells and to generate duty cycle control signals for the N power cells. The duty cycle control signals are applied to the control circuits to adjust the duty cycle of one or more clock signals supplied to the power cells to balance a current loading among the N power cells.
