Abstract
The utility model relates to a three-phase motor drive controller power plate, which comprises a PCB aluminum substrate. Power supply terminals, three-phase terminals and a plurality of parallel field effect power tubes are arranged on the PCB aluminum substrate. The field effect power tubes are connected with the power supply terminals and the three-phase terminals. By means of a copper bar and the terminals, the field effect power tubes are connected through a PCB copper film and soldering tins on the copper film. By using the drain electrode metal plates of the field effect power tubes packaged by TO-220 or TO-262 as the conducting plates and radiation plates, the three-phase motor drive controller power plate has the PCB space saved and also saves the materials. Furthermore, the power plate provided by the utility model has the advantages of small size, large bearing power and convenient installation, etc.
