摘要
特定消谐式逆变器在理论上能有效地消除谐波,但死区设置增加了输出电压的谐波含量。该文通过对特定消谐式逆变器换流机理的分析,研究了感性负载时死区对输出电压的影响,提出了死区的补偿策略,用修正的开关角所对应的控制信号得到理想的输出电压波形。
Selective harmonic elimination inverter can eliminate harmonic effectively in theory, but dead zone increases the harmonic component in output voltage. Based on the operation principle of selective harmonic elimination inverter, effect to output voltage in inductance is investigated and a compensation strategy of dead zone is presented which uses control signals according to modificatory switching angles to gain ideal output voltage waveform.
