Voltage-Source Inverter with Resonance-DC-Link and Variable-Speed Systems for A.C Motor

摘要: 具有共振直流環節的電壓型逆變器是在傳統的PWM硬件開關電路上加一個共振環節,構成高頻、無開關損耗電壓型逆變器。這種電路與目前通用的PWM逆變器相比,具有頻率高、噪音低、開關損耗小、系統體積小、電磁干擾小,有較好的輸出波形和不需要阻尼電路等優點。

Abstract: Adding a resonance link to the traditional PWM inflexible switching circuit, a voltage-source inverter of high frequency and no switching less was formed. Compared with current PWM inverters, this circuit has the advantages of high frequency, low noise, low switching-loss, little system volume, low electromagnetic interference, quite good output wareforms and no need of damping circuit.
