Introduction: This section includes semiconductor controllers and starters for low-voltage AC motors. In addition to simple starting and stopping induction motors, there are many other functions and features. Such as controlled start and stop, manipulation and controlled operation. In this section, the general term “controller” is used when the special characteristics of power semiconductor switching elements are mainly emphasized. When the results of working with power semiconductor switching elements and appropriate overload protection measures are mainly emphasized, the emphasis The characteristics of different configurations use specific names (for example, type l, type HxB, etc.). The general term 'starter',
