Phase Change Converters is an Australian inventor and manufacturer of microprocessor-controlled rotary phase converters, providing reliable three-phase power from single-phase supplies for businesses, farms, workshops and industry across Australia.

At the heart of the Phase Changer is our proprietary microprocessor control technology and software, developed specifically for our converters and continuously refined through real-world experience. Now in its 55th generation of software development, the technology has evolved from feedback and experience gained across more than 10,000 Phase Changer installations and an extraordinary range of machinery, applications and operating conditions.

For many of our customers, three-phase power isn't simply a convenience — it is what allows their machinery and their business to operate. A Phase Changer provides an alternative where utility three-phase power is unavailable, impractical or prohibitively expensive, without relying on a generator for everyday operation.

Designed and manufactured in Victoria since 2005, Phase Changers have been supplied to businesses, farms, manufacturers, schools, universities, government and infrastructure applications throughout Australia. More than two decades later, we remain a specialist Australian family business, continuing to develop, manufacture, service and support the technology we created.

Phase Changer: 3 Phase for Business

Phase Changer is a high performance, efficient and reliable converter ideal for businesses that rely on quality 3 phase power.

Phase Driver: 3 Phase Backup from a Battery

Phase Driver is suitable for single motor applications, 240V input to 3 phase 415V output. It can be powered from an off the shelf UPS to provide critical backup when the utility power fails.

3 Phase to Single Phase Transformers

Have a 3 phase generator and need more single phase 240V output? Then this could be your solution.

Variable Speed Drives (VSD / VFD)

VSD's certainly have their place in motor control. WE offer a complete service , including pre-programming to suit your application.

Compressor Head Pressure Relief Kit

This kit can be fitted to any 3 phase compressor to open the head to atmosphere at start up. In the real world this can mean a 50% drop in in-rush current. A great solution where mains power is limited.

Accessories and Parts

Need spare parts for converters, 3 phase outlets, plug tops etc. Then we can help.

The Story Behind Phase Changer

Phase Changer began with a simple idea: finding a better way to provide reliable three-phase power where only single-phase electricity was available.

Developed by Australian industrial electrician and inventor Mark Bridgman, Phase Changer grew from practical electrical engineering, hands-on experience and solving real problems for machinery owners. The innovation was recognised nationally when Mark and Phase Changer were featured on ABC Television’s The New Inventors.

Phase Changer also travelled beyond Australia. Systems were supplied to the United Kingdom, New Zeland, South Africa, China, Vietnam and Tunisia, including applications powering irrigation pumps on coffee plantations in Vietnam and olive farms in Tunisia. Some of the most memorable feedback came from older women running coffee plantations in Vietnam, who sent Mark notes thanking him for helping solve a problem that had made operating their farms difficult. For Mark, that has always been one of the greatest rewards of Phase Changer — using his knowledge to solve a real problem and seeing the difference it makes to someone’s livelihood.

Despite opportunities to expand internationally, we made a deliberate decision to focus on Australia and remain a small Australian family business. Staying small allows us to remain close to our customers and put our resources into the product, its development and the support we provide rather than the overheads of a large organisation.

More than two decades later, Mark is still hands-on — speaking directly with customers, working through unusual applications and developing solutions when a standard answer isn’t enough. Many customers have stayed in touch with us for years even decades, and some have become very good friends.

For us, Phase Changer has never been simply about selling electrical equipment. There is a particular satisfaction in knowing that something we manufacture can enable a farm, workshop or small Australian business to operate machinery where access to three-phase power would otherwise make it difficult or impossible.

That problem-solving spirit is where Phase Changer began, and it remains at the heart of our family business today.
