摘要:
A power module for an inverter which includes a base which has a plurality of slots are formed thereto, a plurality of building blocks inserted into the slots and power cables interconnecting the building blocks. Further, each of these building blocks is provided with a power element which corresponds to one phase. Thus, each building block in the power module may be replaced individually without having to replace the entire power module in case of a failure in a single power element of the power module.

The present invention provides an apparatus for effectively cooling electric modules such as an inverter and an LDC installed in a hybrid electric vehicle or an electric vehicle. The cooling apparatus for electric modules of a hybrid electric vehicle or an electric vehicle secures a uniform cooling efficiency and achieves an excellent heat radiating efficiency at the same time by realizing a new type of cooling system adapted to separately manage heat transfer in the cooling water passages of first and second electric modules by separating an upper passage of the first electric module and a lower passage of the second electric module using a cooling separator.

The present invention is directed to methods for forming an inverter circuit for operating a drive motor of an electric vehicle, which can more effectively reduce the switching noise generated by a power module during the operation of an inverter.
摘要:
A power cable breaking detection method for a vehicle includes detecting currents of respective phases supplied to a three-phase motor from an inverter through at least a power cable, and a driving speed of the motor, determining whether the respective currents and the driving speed of the motor satisfy power cable breaking detection conditions, determining whether various conditions are satisfied with respect to a cable breaking sensing reference value of a current command performing cable breaking timer counting when the conditions are satisfied, and determining whether a predetermined period has elapsed such that a cable is considered broken when the predetermined period has elapsed.
