摘要

本文提出了一种用于级联多电平逆变器的PWM方案。该方案基于对称规则采样单极PWM，具有多调制波形和单载波。定义PWM开关瞬间的数学方程推导并使用低成本微控制器实现数字化。搭建了一个五电平级联多电平逆变器试验台，验证了该算法的可行性。

An alternative PWM scheme for multilevel voltage source inverter

This work proposes an alternative PWM scheme for cascaded multilevel inverter. The scheme is based on symmetric regular sampled unipolar PWM, with multiple modulating waveforms and a single carrier. Mathematical equations that define the PWM switching instants are derived and implemented digitally using a low-cost microcontroller. A five-level cascaded multilevel inverter test-rig is built to prove viability of the proposed algorithm.
