The disclosure relates to power electronics technology and aims to provide a control method of constant-voltage-gain isolation type bidirectional full-bridge DC/DC converter, which is based on a single-phase-shifting modulation method. By enabling the difference between the M times of the input voltage and primary-referred value of the output voltage to be constantly zero, to realize the control goal that the ratio value between the primary-referred value of the output voltage and the input voltage is constantly M; the ratio value between the primary-referred value of the output voltage and the input voltage is defined as the voltage gain M, wherein an adjusting range is 0.5&#x2dc;2; through introducing a feedforward compensator involving the input and output voltages and the input and output currents, a linear controller of the system is implemented.
