Not shown in), controller is connected respectively with power model, also, each power model is connected with a certain of electromotor, multiple
Power model can jointly complete a certain item function, and such as commutator 104 includes 3 power models, and inverter 106 includes
3 power models, the control instruction of the operation that each power model therein is performed is issued by controller.For example, commutator
104 or inverter 106 in the analogue signal of the power model electric current, voltage and temperature that gather corresponding phase be sent to controller,
The analog signal sampling is obtained corresponding digital signal by controller, corresponding by the analysis output to the digital signal
Control instruction.And, each function of power model is that the control signal sent by controller is controlled in current transformer
's.Because net side power model is parallel connection, with insulated gate bipolar transistor (English：Insulated Gate Bipolar
Transistor, abridge IGBT) as a example by module, the technical problem underlying for existing is that multiple IGBT are directly in parallel, due to control letter
Number and the structural path installed of module is inconsistent that power model can be caused to open the uneven stream of cut-off current.Additionally, can't be real
