3. If you are engaged in maintenance or after-sales, you must know the main circuit diagram, rectification, filtering and inverter of the inverter. Some electronic components must be known, such as rheostat, charging resistor, equalizing resistor, non-inductive capacitor, filtering capacitor, and various optocouplers in the driving circuit, such as 250, 350, 365, 438+020, 365, 438+06. This is the abbreviation, and the functions and pins of these optocouplers must be known. Because in the process of maintenance, it is always necessary to judge the quality of equipment.
