Single Phase Inverter Transformers

UPS systems or home inverters are widely used as an alternative power source. Inverter transformer plays a prominent role in such UPS systems. Using high frequency switching and use of IGBTs is the trend. Impedance matching to the switching devices and efficiency is the Key factor in these Inverter transformers.

We manufacture the inverter transformers as per the specifications of our clients. Our Inverter transformers enable the UPS to deliver more backup time. The Inverter Transformers used in most UPS systems are generally Al wound. We supply the same.

Inverter Transformer : Manufacturing & Research

The Inverter Transformers are made with Super Enamel or DFGC Copper and Aluminum round wires or Rectangular strips of Insulation class, “F” OR “H”. Low loss CRGO / CRNGO stampings are used as per the requirements of customers and their specifications to suit typical applications.

Our team of technical experts evaluate your requirements of power and machinery and suggest a right solution from our existing range of products or develop a customized solution for you. Our solution is aimed at being cost effective with optimum efficiency for enhanced productivity. The experienced Research and Development team supported by a state-of-the-art facility develop customized solutions for your requirements. The aim is always to delight our customers.

Inverter Transformer : Quality control

We follow a zero defect policy. To ensure the 100% implementation of the same, we implement stringent Quality Management System. This QMS works at three levels.

1. Pre assembly: All that forms a part of the final product which is delivered to you is checked for quality individually under the prescribed guidelines and parameters; even before it becomes a part of the final product.

2. Assembly: The quality checked parts then come together to take a form of the final product on the assembly line or the manufacturing area. Here, our In-process Quality Control (IPQC) department personnel ensure the monitoring of quality at every step of the manufacturing process.

3. Ready for Delivery: The final product that is ready for delivery then undergoes a final check that involves checking the product on all the prescribed parameters by our well trained and experienced staff. This is a very critical stage in implementing our ‘zero defect policy’ and ensures peace of mind for our clients.

" We are leading manufacturer and supplier of high performance Transformers & Chokes/Reactors with highest Energy Efficiency resulting in Energy (cost) savings in the Product, where those are used."

“ Manufacturer of Inductors, Line Reactors and Custom Build Single Phase or Three Phase Control & Power Transformers with capacity from 10 VA to 150 KVA ”

Quality Check

All materials that form a part of our products have to pass through stringent Quality checks.

  • Every product is rigorously tested for their electrical parameters
  • Ratio test (No load test)
  • Short circuit test
  • Megger test (Insulation resistant test)
  • High voltage break down test (Flash test)
  • Type test for batch core loss / efficiency
  • Impedance measurement Test
  • Test certificate details on all the tests conducted and results thereof.
