ABSTRACT
 Inverter is the core module of the power electronics for converting a fixed DC voltage as a power conversion module with the AC voltage, It has been applied to a power control and motor control. In this study, we aimed to develop an inverter that is used especially for control of a kind of BLDC motor AC servo motor. The control of the inverter is composed of a circuit for generating a variable frequency, the motor phase voltages of variable amplitude, phase current using a DC voltage Vdc_link. Power switching device that is used for the built-in three-phase bridge circuit in the inverter unit is a high voltage, And For the purpose of the medium-current conduction IGBT devices it is mainly used. IGBT switching element is a tendency to use mainly the driving circuit module, because of the complexity of the gate drive circuit. In this study, we propose a method for designing an inverter of 40kW class using semikron 7 pack IGBT modules, three lower IGBT gate driving module and three upper IGBT gate driving module.
