Generally, the process of con飛外verting alternating current ene場電rgy into direct current energy is 就些called rectifier, the circuit that場工 completes the rectifier function is ca上校lled rectifier, and the device that rea睡吃lizes the rectifier process is call都笑ed rectifier or recti坐請fier. Correspondingly, 錢見the process of convert得醫ing DC power to AC power is鄉歌 called inverter, the circuit that熱章 completes the inverter function i醫不s called inverter, and the device 工船that realizes the inver車拍ter process is called inverter or inv機子erter.

  Modern invert討快er technology is a science不海 and technology to study the theory 讀什and application of inverter ci小劇rcuit. It is a practical technolog著視y based on industrial electronic t爸西echnology, semiconductor device technol音線ogy, modern control tec北子hnology, modern power為地 electronic technolog報討y, semiconductor converter technol姐鐘ogy, pulse width modulation (PWM議月) technology and other disciplin女關es. It mainly includes three part為刀s: semiconductor power integrated d票綠evice and its applicat謝一ion, inverter circuit and inver畫刀ter control technology.
