SiC heating elements: learn more about CD Automation solutions
In the field of high-efficiency heating systems, silicon carbide (SiC) heating elements stand out for their superior performance, and therefore require equally advanced power control solutions.
Silicon carbide is a semiconductor material with a much higher resistivity than metallic materials. The resistance value of these elements at room temperature is quite high, and decreases with increasing temperature to a minimum value of around 600-900°C; at element temperatures above 900°C, the increase in resistivity increases with increasing temperature, as shown in figure.
Silicon carbide (SiC) resistors show a change in their value with temperature and ageing, with the value at the end of their period of use becoming approximately 4 times the initial one.
For optimum handling of SiC resistors, constant power regulation with a VxI transfer feedback is required. On three-phase loads with Silicon Carbide, the use of a VxI feedback is suggested to achieve constant power regulation, necessary to compensate for changes in resistance value with temperature and age of the elements.
CD Automation, at the forefront of control technology, presents the REVEX 1PH and REVO C (1PH and 3PH) product lines specifically designed to optimise the use of SiC elements. These solutions combine precision, energy efficiency and reliability, meeting the needs of industrial applications that require maximum thermal control and optimal energy management.

SiC Touch Panel: the solution that facilitates the control of SiC heating elements
CD Automation has developed a series of tools to facilitate the implementation of applications requiring the control of Silicon Carbide (SiC) heating elements. The philosophy is to use a standard Thyristor Unit with serial communication and to implement the control strategy through a front control panel. This touch screen panel in addition to the universal CD Automation unit allows you to work with all firing and control modes, removing all the risks that could arise from selecting an unsuitable control type
This solution brings several advantages. Through an operator interface connected to our communication-equipped SCR units, the following benefits can be achieved:
- Automatic configuration and tuning of the thyristor unit
- Automatic tuning of Power Control mode VxI
- Message on the need to replace SiC elements because they are at the end of their life
- Automatic switch from Voltage to VxI control mode when the element temperature is the correct one
- Automatic tuning procedure of Heather break alarm to diagnostic partial or total load failure
- Diagnostic of fuse failure and Thyristor in short circuit
- Recent and Historical Curve of following process variable
- Power density W/cm2
- Load voltage
- Load current
- Power to the load
- Resistance value curve with new element
- Time elapsed from start to actual resistance value
Two different modes to drive SiC:
- Burst Firing with automatic adjustment of Power Limit
- Phase Angle with transfer from voltage to Power control mode
