| 摘 要： | 利用游标卡尺的工作原理将多个开关频率不同的逆变器串联，在每个逆变器开关频率不高的情况下得到高精度的输出波形，有效地降低了开关损耗、提高逆变器效率并延长了开关器件的寿命。最后，用仿真技术将游标原理逆变器与传统逆变器相比较：游标逆变器在开关频率仅为传统逆变器开关频率1／4的情况下输出与传统逆变器相同分辨率的电压。

| Abstract: | Applying vernier principle,multi inverters are connected in series to settle down the incompatibility of output voltage precision and switching frequency. The high precision of output wave is obtained while each inverter operates at a low switching frequency,which lowers the switching losses,enhances the inverter efficiency and thus prolongs the life of switch. The vernier-based inverter and conventional inverter are compared through simulation. Results show that,to generate voltages with same resolution,the vernier-based inverter operates at one-fourth switching frequency of conventional one. |
