BIS Certification for All Types of Power Semiconductor - Process, Fees, Docs

Updated on August 08, 2025 02:41:45 PM

Power semiconductor converters are some of the most important devices in today’s electrical engineering for enabling efficient conversion of electrical energy. They are present in applications that range from conventional solar panels and wind power conversion, to electric vehicle charging, and industrial motors to name a few, to ensure proper control of the power and increased energy conversion efficiency. We classify power semiconductor converters into four main categories: AC-DC rectifiers, DC-AC inverters, DC-DC converters, and AC-AC converters To distinguish, each type has its particular application based on the needs of a particular system.

These gadgets are controlled and recognized in India by the Bureau of Indian Standards BIS, to ensure that such gadgets fulfill protection and efficacy standards. Certification to these products is a very compulsory factor that any company planning to so supply products to the Indian market due to its significance in showing compliance to the regulation as well as market acceptance. Therefore, it helps power electronics industry stakeholders to comprehend the manufacturing processes, performance prescriptions, testing protocols, and BIS certification. In this blog where these facets shall be discussed in detail about the relevance of power semiconductor converters and their contribution to the Indian technical progress.

What are the Power Semiconductor?

Power semiconductor converters can be categorized as one of the basic components in current electrical systems globally especially due to their prime function of transforming electrical energy from one form to the other. They have a central function in a range of applications, from renewable energy systems to electric vehicles to industrial machinery. These converters employ diodes, transistors, and thyristors to regulate and facilitate power electrical power appropriately.

BIS Certification Process of Power Semiconductor

The BIS certification process for All types of Power Semiconductor Converter and (or) their assemblies /sub-assemblies /components.

Step 1: Application Submission

Applications are filled including relevant documents that outline the production processes of the manufacturers.

Step 2: Factory Inspection

A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.

Step 3: Product Testing

The samples from the production batches are analyzed at the BIS-accredited laboratories.

Step 4: Issuance of License

As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.

Step 5: Surveillance Audits

To sustain the standards practice, normal assertions are carried out.

This is a process that manufacturers need to understand so that they can get an efficient certification.
