Beijing Oriental Jicheng Co.,Ltd.
Beijing Oriental Jicheng Co.,Ltd. (Stock code :002819). As a leading domestic testing technology and science and technology service company, we have been deeply engaged in the field of measurement for many years, and strive to create an industrial platform and ecosystem to promote the transformation of scientific and technological achievements.
NEBU has gradually formed an industrial closed loop from software to hardware, from product development to system integration, from testing services to talent training, and actively enabled the development of the new energy automobile industry! Actively comply with the "electrification", "intelligence", "network", "sharing" of the new four trends; Pay close attention to industry standards, continuous research and development, continuous innovation; Centering on the technical direction of "three high, three smart and one safety", we tailor a "one-stop" solution for industry users from signal level simulation test to power level performance test, from parts to system level, and then to vehicle level.
Product 1
Development technology/material/manufacturing process namePower Hardware-in-the-Loop based on Electric Machine Emulator
Innovation Highlights1. The inverter unit of EME adopts the parallel topology structure of cascade coupling, which can simulate harmonics at the maximum frequency of 600kHz, much higher than the switching frequency of MCU and beneficial to the simulation of higher harmonics, glitches and fault injection; 2. Real-time signal display is beneficial to waveform observation, data recording and playback; 3. The real-time acquisition system designs a circuit for the high-speed and high-voltage silicon carbide switch to eliminate the influence of the sampling circuit; 4. The FPGA board simulates various types of motor model with the simulation calculation speed assured.
