交流變頻調(diào)速技術(shù)是強(qiáng)弱電混合，機(jī)電一體的綜合技術(shù)，既要處理巨大電能的轉(zhuǎn)換（整流、逆變），又要處理信息的收集、變換和傳輸，因此它必定會(huì)分成功率和控制兩大部分。前者要解決與高壓大電流有關(guān)的技術(shù)問題，后者要解決的軟硬件控制問題。因此，未來高壓變頻調(diào)速技術(shù)也將在這兩方面得到發(fā)展，其主要表現(xiàn)為：
① 高壓變頻器將朝著大功率，小型化，輕型化的方向發(fā)展。
② 高壓變頻器將向著直接器件高壓和多重疊加（器件串聯(lián)和單元串聯(lián)）兩個(gè)方向發(fā)展。
③ 更高電壓、更大電流的新型電力半導(dǎo)體器件將應(yīng)用在高壓變頻器中。
④ 現(xiàn)階段，IGBT、IGCT、SGCT仍將扮演著主要的角色，SCR、GTO將會(huì)退出變頻器市場(chǎng)。
AC variable frequency speed regulation technology is a comprehensive technology that combines strong and weak electricity and electromechanical integration. It not only deals with the conversion of huge electric energy (rectification and inversion), but also deals with the collection, transbation and transmission of inbation. Therefore, it must be divided into two parts: success rate and control. The ber should solve the technical problems related to high voltage and large current, and the latter should solve the software and hardware control problems. Therefore, the high-voltage variable frequency speed regulation technology will also be developed in these two aspects in the future, mainly as follows:
① High voltage inverter will develop towards the direction of high power, miniaturization and light-weight.
② High voltage frequency converter will develop towards direct device high voltage and multiple superb (device in series and unit in series).
③ New power semiconductor devices with higher voltage and current will be used in high-voltage inverters.
④ At this stage, IGBT, IGCT and SGCT will still play a major role, and SCR and GTO will withdraw from the inverter market.
⑤ The application of speed sensorless vector control, magnetic flux control and direct torque control will be mature.
⑥ Fully realize digitalization and automation: beter self setting technology; Process self optimization technology; Fault self diagnosis technology.
⑦ Using 32-bit MCU, DSP, ASIC and other devices, the converter can achieve high-precision and multi-function.
