提出了一种新的功率逆变电路死区补偿方法。该方法利用基于载波的正弦脉宽调制技术产生具有死区校正能力的逆变器功率开关的驱动信号。该方法能够消除死区效应，减小逆变器输出电流的波形失真，提高输出电流的基波分量幅值。对所提出的方法进行了分析。通过计算机仿真研究了该方法的工作原理，并对其性能进行了测试。通过对H桥式电压型逆变器电路的实验测试，验证了该方法的有效性。计算机仿真和样机实验数据表明，该方法对电压型功率逆变器电路的死区补偿效果良好。
A new dead-time compensation method of power inverter circuits is suggested and presented in this paper. The proposed method utilizes carrier based sinusoidal pulse width modulation technique to produce driving signals of the inverter power switches with dead-time correction capability. The proposed method able to eliminate dead-time effects such as reducing the waveform distortion of the inverter output current, and increasing the fundamental component amplitude of output current. An analysis of the proposed method is presented. Some computer simulations were carried out to investigate the principle operation, and to test performance of the new method. The developed method was validated through experimental test of H-bridge voltage source inverter circuits. The data obtained from the computer simulation and prototype experiments have confirmed that that the proposed method worked well compensating the dead-time in the voltage source power inverter circuits.
