A method controls a boost converter having N switching cells using synchronous pulse width modulation, in which N is a natural integer that does not equal zero. The method includes: measuring input voltages and output voltages of the boost converter; determining an output vector to define a representation of a linear state of the boost converter; calculating the variation in power of the electrical load; determining the N duty factors as a function of the second derivative of the output vector, the derivative of the power of the electrical load, and the ratio between the input voltage and the output voltage that have been measured; and controlling each switching cell of the converter depending on the duty factor that has been determined.
