Abstract:
1. A method of controlling at least one transistor of a DC voltage converter to regulate an output voltage of the DC converter, the method comprising: determining whether the output voltage of the DC converter is within a first or second voltage range; if said output voltage is within said first voltage range, generating a first control signal using a first control method performed by a first controller, said first controller receiving a first feedback signal indicative of the output voltage and determining the first control signal for restoring a desired output voltage value, the first control signal based on a value of the first feedback signal; and if said output voltage is within said second range, generating a second control signal using a second control method performed by a second controller, said second controller receiving the output voltage and determining the second control signal for restoring the desired output voltage value, the second control signal based on a value of the second feedback signal.
