BIS Scheme X Certification for Power Semiconductor Converters and Their Components

bis-scheme-x

Power Semiconductor Converters are integral to the operation of contemporary electrical systems, providing the essential functionality of transforming electrical energy between various forms. These devices play a critical role across industries—from renewable energy, electric mobility, and automation to household electronics. To ensure product safety, quality, and standardization in the Indian market, the Bureau of Indian Standards (BIS) has mandated certification under Scheme X for all types of Power Semiconductor Converters and their parts.

Below is a complete breakdown of the certification scope, process, compliance requirements, and the implications of this regulatory development for manufacturers and importers.

Understanding Power Semiconductor Converters

Power semiconductor converters are electronic devices that utilize semiconductor elements like IGBTs, MOSFETs, thyristors, and diodes to manage and convert electrical energy. Key applications include:

DC to AC conversion (Inverters)
AC to DC conversion (Rectifiers)
DC to DC conversion (Choppers)
AC to AC conversion (Cycloconverters)
Variable frequency drives (VFDs)
Uninterruptible Power Supplies (UPS)
Solar and wind energy systems

These converters are widely adopted in sectors like energy, electric transportation, smart manufacturing, and electronics.

Regulatory Framework: BIS Scheme X

To promote safety and quality across the electrical machinery sector, BIS introduced Scheme X Certification under the BIS Conformity Assessment Regulations, 2018. This framework, launched on 16th March 2022, mandates standardized evaluation of equipment through independent testing and factory audits.

The Omnibus Technical Regulation Order (OTR), 2024, issued by the Ministry of Heavy Industries, makes it mandatory for all domestic and foreign manufacturers to obtain BIS certification for these products before 28th August 2025.

Scope of Certification

Types of Converters:

Industrial-grade inverters and converters
Rectifiers and bridge modules

This extensive coverage ensures that not only the complete systems but also all essential subassemblies meet the required performance and safety standards.

Why BIS Certification Matters

Regulatory Requirement: After 28 August 2025, it will be unlawful to manufacture, import, or sell non-certified converters in India.
Enhanced Safety: Compliance ensures products are protected against faults like overheating, voltage surges, and fire hazards.
Expanded Market Access: Certified equipment becomes eligible for public and private procurement contracts requiring BIS approval.
Brand Credibility: The BIS mark enhances customer trust, providing assurance of adherence to Indian safety and quality norms.

Step-by-Step Certification Process

Product Identification: Determine if your converter or component falls under the mandatory BIS categories.
Documentation Preparation: Gather key documents including:
- Product specifications and circuit diagrams
- Manufacturing flow and quality control protocols
- Raw material list and safety features
- Test reports from BIS-approved labs
Application Filing: Submit your application through the BIS online portal and complete the required fee payment.
Product Testing: Send samples for testing at BIS-recognized laboratories. Tests include:
- Dielectric strength
- Efficiency and thermal response
- Harmonics, voltage regulation, and fault handling
Factory Audit: BIS officials visit the manufacturing unit to inspect:
- Production consistency
- In-house testing setup
- Quality control processes
Grant of License: Once your product clears testing and inspection, BIS grants the license and allows the use of the BIS Standard Mark.
Post-Certification Surveillance: Regular audits and periodic sample testing ensure long-term compliance.

Risks of Non-Compliance

Manufacturers and importers who fail to meet the BIS Scheme X requirements by the 28th August 2025 deadline may face:

Prohibition on sales or imports
Product recalls or seizures
Fines and legal penalties
Brand reputation damage and loss of market trust

Conclusion

The BIS Scheme X Certification for Power Semiconductor Converters is more than a statutory obligation—it's a vital step towards ensuring safe, efficient, and globally competitive electronic infrastructure. With less than a year remaining, manufacturers must act swiftly to initiate compliance, align their production systems, and avoid regulatory consequences.
