ITG Electronics, a manufacturer of inductors and transformers, is expanding its capabilities in relation to the growing electric vehicle (EV) sector to include Power Custom DC-to-DC LLC Transformers. This pivot coincides with an expanded set of other components the company offers relevant to EV production — including resonant inductors, power factor correction chokes, and current sense transformers.
Conventional line frequency transformers are constrained by efficiency limitations. Medium to high-frequency transformers based on power converters can achieve more reliable power conversion in a smaller footprint, and have understandably become popular in various industrial applications.
Among these, unregulated resonant converters, LLC and CLLC resonant converters — with fixed voltage conversion ratios and operating at resonant frequency (also known as DC transformers or DCXs) — are attractive owing to their high-efficiency characteristics.
However, there are issues associated with DCXs in real applications, the most prominent being regulation capability and automatic resonant frequency tracking capability. Manufacturers are seeking reliable suppliers that can provide engineering support from initial development phases through large-scale line production. This is a need ITG Electronics addresses with its latest additions.
For example, ITG’s 3 kW LLC DC/DC Converter has a power density of 146.3 W per square inch, and a 98% efficiency rating backed by the company’s extensive in-house testing. ITG Electronics also offers high-current boost inductors, PFC chokes, common mode chokes, and custom CLLC transformers for 400 and 800 V OBC power systems.
