结果表明，尽管调制器输出具有准随机特性，但同步增量调制（DM）系统的输出电流谐波失真和平均开关频率仍可以解析计算。在链路频率恒定和链路与输出频率之比较大的假设下，推导了三相Σ-Δ调制、基于空间矢量的Σ-Δ调制和电流调节DM的结果。结果适用于任何形状的逆变器输入电压（包括直流）。比较了谐振环节逆变器与传统硬开关脉宽调制（PWM）逆变器的输出电流谐波畸变率。&lt;<ETX>&gt;
It is shown that the output current harmonic distortion and average switching frequency of synchronous delta-modulation (DM) systems can be calculated analytically in spite of the quasi-stochastic behavior of the modulator output. Under the assumption of constant link frequency and a large ratio of link to output frequency, results are derived for three-phase sigma-delta modulation, space-vector-based sigma-delta modulation, and current regulated DM. The results hold for any shape of the inverter input voltage (including DC). The output current harmonic distortion of resonant link inverters is compared with that of conventional hard switching of pulse width modulation (PWM) inverters.<<ETX>>
