How can the initial EMC design of an energy storage system PCS avoid the need for later rectification?

Systematic EMC design in the early stages of PCS development is crucial to avoiding costly and time-consuming rectification later. Key points for early design:

1. Establish EMC design specifications: Based on product standards, topology, and power ratings, pre-define detailed PCB layout, grounding, shielding, filtering, and protection design specifications.

2. Simulation analysis: Utilize simulation tools to model and simulate switching waveforms, power loop parasitic parameters, filter impedance, and chassis shielding effectiveness to predict potential problems and optimize.

3. Refer to mature designs: Borrow proven modular designs, such as using tested driver boards and filter modules.

4. Pre-select key components: Select and evaluate key EMC components in advance, such as common-mode inductors, TVS diodes, and shielding materials.

5. Design review: Organize cross-departmental EMC design reviews to ensure that schematics, PCB layouts, and structural designs comply with specifications.

6. Prototype building and pre-testing: Build prototypes as early as possible and use pre-testing tools for screening and optimization. Treat EMC as a concurrent engineering process throughout the entire development cycle, rather than as an afterthought.
