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