Abstract:A novel diode clamped three level dual-Boost reversible PWM rectifier is proposed in this paper. This topology is improved based on the dual-Boost PWM rectifier inherits the advantages of high reliability and efficiency due to no hidden danger of shoot-through and no reverse recovery problem of body diodes of power switches. In addition, it also overcomes the shortcuts of dual-Boost PWM rectifier, that is the voltage stresses of power switches reduce to half the output voltage. This leads to more suitable for high-voltage occasions. The hysteretic current control is involved in this paper and no loop-current operation is realized. The switching logic is deduced with the detailed analysis of the operational scheme. After that, the rule of filter designing is analyzed. Simulation and experimental results verify the correctness of theoretical analysis.
