The development of inverter power supply technology has always been closely linked with the advancement of power devices and their control technologies, undergoing five stages since its inception. Below, the 400HZ power supply editor gives you a brief introduction:
In the 1950s and 1960s, the birth of the thyristor SCR paved the way for the development of sine wave inverters.
In the second phase, in the 1970s, the introduction of the Gate Turn-Off (GTO) thyristor and Bipolar Junction Transistor (BJT) facilitated the development and application of inverter technology.
In the three stages, the birth of power devices such as power field-effect transistors, insulated-gate transistors, and MOS-controlled thyristors in the 1980s laid the foundation for inverters to develop towards large capacity.
In the 1990s, the development of microelectronics technology facilitated the application of emerging control techniques such as vector control, multi-level conversion technology, repetitive control, and fuzzy control in the inverter field, significantly boosting the advancement of inverter technology.
Five Stages: At the beginning of the 21st century, the development of inverter technology has been continuously improved with the advancement of power electronics technology, microelectronics technology, and modern control theory. Inverter technology is now evolving towards high-frequency, high-efficiency, high power density, high reliability, and intelligence.
