With the increasing diversification of user needs, the application fields of the frequency converter market are constantly expanding, and more and more new technologies and materials are being applied in the development of frequency converters. Frequency converter products are also accelerating their development towards intelligence, customization, integration, and energy conservation.

Due to the relatively late start of China's low-voltage frequency converter field compared to developed countries, foreign brands have taken the lead in the market. In the late 1980s, frequency converter products from Japanese companies such as Yaskawa Electric, Mitsubishi Electric, and Fuji Electric successively entered China, and the frequency converter market was initially dominated by Japanese brands.

The variable frequency soft start industry is in a growing period, with a large market space and a wide range of potential application areas.

The motor soft starter is a new type of starting equipment designed and produced using power electronics technology, microprocessing technology and modern control theory with today's international advanced level. This product can effectively limit the starting current when starting an AC asynchronous motor. It can be widely used in loads such as fans, water pumps, transportation and compressors. The ideal replacement product for pressure equipment.

A novel motor control device that integrates motor soft start, soft stop, light load energy saving and multiple protection functions. It is called Soft Starter abroad. Its main components are three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. Different functions can be achieved by using different methods to control the conduction angle of the three-phase parallel thyristor so that the input voltage of the controlled motor changes according to different requirements.

We all know about frequency converters and soft starters, but do you know their differences and their respective advantages and disadvantages? Frequency converters control electrical equipment by adjusting frequency, and can regulate speed and start, such as variable frequency pumps used in industry.
