Abstract:
Three-level active neutral-point-clamped ( ANPC) topology is a novel multi-level topology, which can overcome the disadvantages of diode clamped topology and capacitor clamped topology. The working state of the three-level ANPC converter was analyzed. The conduction loss and switching loss of devices were studied. An optimization control strategy using space vector pulse width modulation ( SVP-WM) was proposed to balance loss between different devices in a three-level ANPC converter. The opti-mized strategy can keep the advantage of SVPWM,and balance the neutral-point potential. Compared with traditional control strategy,the control strategy can reduce the complexity of the traditional ANPC converter algorithm and reduce the number of temperature sampling circuit. The simulation and experi-mental results are provided to verify the effectiveness of the proposed control strategy.
