BIS Scheme X Certification for Power Semiconductor Converters

Power Semiconductor Converters are the foundation of modern electrical and electronic systems. These devices enable efficient control and conversion of electrical energy across a wide range of applications, from renewable energy systems and electric vehicles to industrial automation and consumer electronics. Given their critical role and increasing usage in India’s energy and industrial ecosystems, the Bureau of Indian Standards (BIS) has made BIS certification for Power Semiconductor Converters mandatory under the Scheme X Certification framework.

Let’s understand everything you need to know about BIS Scheme X certification for Power Semiconductor Converters, including its scope, benefits, the application process, key compliance requirements, and more.

What Is a Power Semiconductor Converter?

A Power Semiconductor Converter is an electronic device that converts electrical energy from one form to another using semiconductor components such as diodes, thyristors, transistors, and IGBTs. These converters are typically used in:

They are widely used in power grids, electric vehicles, smart manufacturing, railways, and consumer electronics.

BIS Scheme X Certification: A Regulatory Milestone

To strengthen quality assurance across the machinery and electrical equipment sectors, BIS introduced Scheme X Certification under the BIS Conformity Assessment Regulations, 2018. This initiative was officially launched on 16th March 2022.

The Ministry of Heavy Industries, via the Omnibus Technical Regulation Order, 2024, has mandated that all manufacturers (domestic and international) must obtain BIS certification for Power Semiconductor Converters and their sub-assemblies/components by 28th August 2025.

Scope of BIS Certification for Power Semiconductor Converters

This certification applies to all types of power semiconductor converters and their assemblies/sub-assemblies/components, including:

It also extends to components and modules such as:

Importance of BIS Certification for Power Semiconductor Converters

1. Regulatory Compliance

After 28th August 2025, it will be illegal to import, sell, or manufacture non-certified power converters in India.

2. Safety and Reliability

Certification ensures these devices comply with safety and performance benchmarks, reducing the risk of failure, overheating, or fire.

3. Market Access

Certified products gain immediate access to government and private sector tenders and markets requiring mandatory BIS certification.

4. Consumer Trust

BIS-certified equipment provides assurance of quality and conformance, increasing trust among end-users and industry stakeholders.

BIS Certification Process under Scheme X

Step 1: Classification & Applicability

Identify the type of converter or component you manufacture. Check if it falls under the mandatory BIS Scheme X certification list.

Step 2: Documentation

Prepare necessary documentation:

Step 3: Application Submission

Apply online through the BIS portal, submit forms, and pay the required certification fees.

Step 4: Product Testing

Send product samples to a BIS-approved lab for testing against the prescribed standards. Testing covers:

Step 5: Factory Audit

BIS officials conduct a factory inspection to assess manufacturing capabilities, quality assurance systems, in-house testing labs, and consistency in production processes.

Step 6: Grant of License

Once the factory audit and product testing are successful, BIS issues a license and allows the use of the Standard Mark on approved products.

Step 7: Surveillance and Renewal

Periodic surveillance audits and random testing ensure continued compliance. The license is renewable after 1–2 years, subject to re-verification.

Benefits of BIS Scheme X Certification for Power Semiconductor Converters

Consequences of Non-Compliance

After 28th August 2025, manufacturers and importers who fail to obtain BIS certification for Power Semiconductor Converters may face:

Conclusion

The BIS Scheme X certification for Power Semiconductor Converters is not just a regulatory formality—it's a strategic move towards safer, higher-quality, and globally competitive Indian manufacturing. With the deadline set for 28th August 2025, manufacturers must initiate the certification process immediately.

Whether you're producing inverters, rectifiers, converters, or any semiconductor-based power control units, BIS certification will soon become your passport to operate in the Indian market.
