Abstract
The present invention is related to a method for controlling a high frequency dual bridge DC/DC power converter of nominal frequency (f) and nominal power (P), in a wide range of input voltage and with power overload capacity up to 200%, said method comprising a step of varying, in a range up to the value of π radians, a first phase shift (φ) between the voltage of the full bridge and the voltage of the half bridge, while—varying the operation frequency (f) simultaneously with the said first phase shift and/or—inducing a second phase shift (φ) between the voltages of the two half bridges or branches constituting the full bridge, modifying thereby the first phase shift (φ) between the voltage of the full bridge and the voltage of the half bridge and/or—decreasing the operation frequency (f) towards the LC resonance frequency (f) of the circuit, so as to minimize the switch losses in the DC/DC converter during operation.
