Motor Control Unit (Power Inverter) - CP Series for High Voltage EV Application
The innovation of CP Series motor control unit (MCU) with DSP-based control is specifically designed for electric propulsion vehicles, embedded with efﬁcient IGBT module for high power density and reliability. Its compact and robust design is suitable for various types of electric vehicle e-Drive system integration, including pure battery EV and plug-in hybrid EV.
MCU conﬁgures motor speed and torque after receiving comments from VCU (vehicle control unit) via CAN-bus communication. The MCU converts battery pack DC power source to AC power supply to drive propulsion motor. During vehicle braking, it can regenerate DC power back to battery pack for charging. Efficient cooling system enables its high power density and performance. Protection includes against over current, over voltage and ov er temperature. Various electrical and environmental tests are passed to meet international standards.
CP series also coms with integrated dual-mode motor control unit: one larger power controller for traction motor and one smaller power controller for integrated starter generator (ISG). Main appliction is PHEV, enabling four (x4) driving modes for the vehicle. ISG controller can start the engine of the range extender, control the ISG, and convert AC power to DC which charges the battery pack, or can provede direct DC power to traction motor MCU for lower speed driving.
CP Series MCU provides maximum performance, efficiency, endurance and reliability for electric propulsion application, making electric vehicle drive more accountable.
