General information
- Short Summary
- A Korean SME has developed a world-first EMI IC that replaces the inductor of passive EMI filter. Combined with the passive choke, the company has been developing innovative EMI filter technology that dramatically reduces cost, space and heat generation compared to existing EMI solution. The company is seeking technical cooperation partners interested in adopting next-generation EMI reduction solutions that address key design challenges in diverse electronic applications.
- Full Description
-
As electrical systems become increasingly dense and high-power electrical devices are widely used recently such as electric vehicle, industrial inverter, etc., mitigating EMI is a critical system design consideration for manufacturers. Without proper mitigation, the interfering signals can system errors and prevent circuits from operating as designed.
So far, the passive EMI solution including capacitors, inductors, and inductive chokes is normally used for mitigation of EMI. However, for high-power electric devices, the filter cost is dramatically increased because larger filter for more attenuation means more money. In addition, especially for home appliances such television, the filter takes up large board area, preventing the manufacturers from making the thin products that customers want.
To solve above problems, Korean SME has developed IC-based active EMI filter solution which is cheaper, lighter, smaller, and generating lower heat than passive EMI solution in 2022. With unique insulation structure and the noise compensation algorithm, this IC EMI filter solution has shown excellent results from tests with global electronics, aerospace, and automotive companies.
Recently, a Korean SME has developed an all-in-one EMI filter solution that combines a proprietary IC-based active EMI filter with a passive choke. Because it doesn't require additional components such as a current transformer and an injection transformer, this solution can provide great benefits to consumer electronics manufacturers, especially for applications where compact design is a key competitive advantage, such as slim TVs and other space-constrained home appliances.
The Korean SME is seeking European partners which are interested in new EMI reduction solutions for developing slimmer home appliances under commercial agreement with technical assistance agreement. - Advantages and Innovations
-
- Active EMI filter achieves significant size and weight reduction compared to conventional passive filters, enabling optimized product designs
- Excellent EMI suppression performance in high-frequency bands, making it highly effective for high-speed switching power systems
- Generates minimal heat, reducing the need for heatsinks or thermal management, and enhancing overall system reliability
- By reducing the quantity of passive components through the replacement of traditional passive parts, it offers clear cost benefits to customers.
- In addition, recently developed ‘Active Choke’ (integrated IC and Passive choke) Solution is expected to be resistant to temperature variation and oscillations
- Since the Active Choke eliminates the need for additional components such as current and injection transformers required in conventional active solutions, it offers even greater advantages in cost and space efficiency. - Stage of Development
