Based on a bidirectional voltage mode high frequency link inverter with active clamp, a novel unipolar modulation strategy was proposed by modulating the triangle carrier wave and two inverse sinusoidal modulation waves. It is no need of checking the pole of the output voltage to switch the control logic signals for realizing seamless four-quadrant operation, and it is able to eliminate the distortion of output voltage at zero-crossing. In addition, double closed-loop digital control with load current feed-forward was designed to improve static and dynamic response for the whole system. Theoretical analysis simulation and experimental results referring to a laboratory prototype (3kVA) indicate that the proposed modulation and control scheme are promising for the applications of inverter.

针对有源钳位双向电压型高频链逆变电路拓扑,研究了一种新型单极性SPWM调制策略,采用对称三角载波与两个相位相反的正弦调制波调制产生所需的控制逻辑信号,该调制策略不需要根据输出电压极性信号来切换控制逻辑就能够实现四象限工作和各象限之间的平滑过渡,克服了原有的单极性调制在输出电压过零点畸变大的缺点。文中还设计了具有负载电流前馈的电压电流双闭环数字控制方案,电流内环可提高系统的稳定性,负载电流前馈能够提高系统抗负载扰动的能力,改善系统的动静态性能。在理论分析和仿真研究的基础上,设计制作了3kVA实验样机,实验结果验证了理论分析的可行性和系统设计的有效性。
