The development of inverter power supply technology has always been closely integrated with the advancement of power devices and their control technologies, having gone through five stages since its inception.
In the 1950s and 1960s, the birth of the thyristor SCR paved the way for the development of sine wave inverters.
In Phase Two: The introduction of the GTO (Gate Turn-Off) thyristor and the bipolar junction transistor (BJT) in the 1970s led to the development and application of inverter technology.
In the 1980s, the birth of power devices such as power field-effect transistors, insulated-gate transistors, and MOS-controlled thyristors laid the foundation for inverters to develop towards high capacity.
In the 1990s, the development of microelectronics technology facilitated the application of newly emerging control techniques, such as vector control, multi-level conversion, repetitive control, and fuzzy control, in the inverter field. This significantly accelerated the advancement of inverter technology.
Five Phases: At the turn of the 21st century, the development of inverter technology has continuously improved with the advancement of power electronics, microelectronics, and modern control theory. Inverter technology is now heading towards high-frequency, high efficiency, high power density, high reliability, and intelligence.
