Abstract—In order to solve the problems existed in the field of high power applications such as voltage stresses and harmonic interferences of the two-level AC/AC converter. A new kind of high frequency isolated full-bridge three-level AC/AC direct converter is proposed. The converter has many advantages such as two-stage power conversions, simple topology and, low voltage stresses. The topology of circuit, operational principle and six kinds of operational strategy are deeply analyzed. The control method of SPWM, which is based on instantaneous voltage value feedback, is used to respond fast to the change of input and output voltage. The control method of converter driving signal, which is from the comparing of four carrier waves and error magnification signal, is summarized. The circuit is simulated by saber and the result indicates that the wave of the converter is improved; however the harmonic and voltage stresses are reduced.
