The invention provides a bidirectional inverter motor controller which comprises a capacitor shell, a cooling shell and a top cover which are connected in sequence. A bus capacitor is arranged in thecapacitor shell, a driving unit, a double-layer cooling mechanism and a power generation unit are arranged in the cooling shell, and a water inlet connector and a water outlet connector are arranged at the first side of the cooling shell. A signal connector, a first high-voltage connector and a second high-voltage connector are arranged at the second side of the cooling shell, and a control unit is arranged at the top of the driving unit and controls the driving unit and the power generation unit through the signal connectors. The bus capacitor is connected with the driving unit and the powergeneration unit through a first copper bar, the driving unit is connected with a driving motor through a first three-phase copper bar, and the power generation unit is connected with a generator through a second three-phase copper bar. The bidirectional inverter motor controller is integrated, is small in size and light in weight and is convenient for the whole installation; by arranging the double-layer cooling mechanism, the heat dissipation efficiency is improved, the service life of the controller is prolonged, and the size and the mass of the controller are reduced.
Description
technical field [0001] The invention relates to the technical field of motor controllers, in particular to a bidirectional inverter motor controller. Background technique [0002] As vehicle exhaust emission standards become more stringent, the development prospects of extended-range electric vehicles are becoming brighter. The bidirectional inverter motor controller is connected with the generator and the drive motor at the same time, and is used to control the start, operation, advance and retreat, speed, and stop of the vehicle, which can effectively improve the fuel economy of the vehicle, and is one of the three core components of the electric vehicle. [0003] The dual-inverter motor controller in the prior art is large in size, complex in internal structure, high in cost, and inconvenient for vehicle layout; in addition, its internal cooling structure is complex and its heat dissipation effect is not good, and the controller is easily damaged if it is used at high tem...
