The invention discloses a green power converter which omits the pulse width modulation (PWM) technique in the traditional power converter, does not have high-frequency power device, does not generate EMI interference, simultaneously adopts the symmetry basic primitive (SBP) technique, the amplitude high modulate (AHM) technique and the dynamic rectification (DR) technique, and only needs to perform traditional power conversion on a small part of the input power so as to acquire the whole output power, namely that a large part of the output power neither need traditional power conversion nor need to pass through a magnetic core transformer. The input AC voltage neither needs to be rectified and filtered nor has large inductance and large capacitance, thus the power factor is 1, and the total harmonic distortion (THD) is 0. A transformer secondary side adopts dynamic rectification, can acquire a DC circuit, and can also acquire an AC voltage. The circuit complexity, the power consumption and the failure rate of the whole green power converter are greatly lowered, and the power converter can be applied in all the fields to replace the traditional power converter.
