The new alternatives in power conversion

Power conversion is familiar in most consumer and industrial technologies, which typically use AC adapters to convert to DC and supply the required voltage. However, while the method of conversion allows a heater to operate at a given set temperature, it receives the full voltage when turned on, which can cause damage over time in some cases. Other solutions, such as phase-angle controllers and DC power supplies also have their own setbacks, making power conversion a tough task. Stan Breitlow discusses the new alternative in power conversion.

Decarbonising petrochemical refining

Petrochemical processes have traditionally been heated with fossil fuels, but pressure is building to mitigate carbon dioxide emissions and advance long-term decarbonisation goals. Fossil fuel heated processes leave big shoes to fill when it comes to thermal processes, so electric process heaters often raise two big questions: how big can an electric heater be? And what is required to maintain proper control of large electric heaters? Here Dennis Long answers these questions and explains why opting for electric is crucial.

Enabling smaller and safer medical devices

Healthcare organisations are increasingly moving patients to home care settings to reduce the pressure on traditional healthcare facilities, especially since the COVID-19 pandemic. However, this has been a double-edged sword for medical device manufacturers. On one hand, it has meant a boom in the market for certain home medical devices, but it has also led to greater scrutiny of devices and increasingly stringent safety standards. Andy Selvy explains how and why medical device manufacturing needs a new approach.
