交流变频调速技术是强弱电混合，机电一体的综合技术，既要处理巨大电能的转换（整流、逆变），又要处理信息的收集、变换和传输，因此它必定会分成功率和控制两大部分。前者要解决与高压大电流有关的技术问题，后者要解决的软硬件控制问题。因此，未来高压变频调速技术也将在这两方面得到发展，其主要表现为：
① 高压变频器将朝着大功率，小型化，轻型化的方向发展。
② 高压变频器将向着直接器件高压和多重叠加（器件串联和单元串联）两个方向发展。
③ 更高电压、更大电流的新型电力半导体器件将应用在高压变频器中。
④ 现阶段，IGBT、IGCT、SGCT仍将扮演着主要的角色，SCR、GTO将会退出变频器市场。
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, transbbbbation and transmission of inbbbbation. Therefore, it must be divided into two parts: success rate and control. The bbbber 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 superbbbbbbbb (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: bbbbbeter 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.
