Traditionally, proportional control of electric heater elements is accomplished with thyristor (e.g., SCR or Triac) based electronic switches. While these can be effective in controlling the amount of heat delivered, they often present issues with power factor and harmonics presented to the utility power line, excessive electronic noise which can adversely affect other nearby equipment, as well as complex control requirements and increased control latency.
An alternate approach to controlling delivered power and heat, leveraging high-frequency switch mode technology, is presented in this session. Along with being an exact control method, this alternate approach addresses the performance issues of previous methods.
In this webinar you will learn the following:
- Operational considerations of thyristor-based circuits
- Opportunities for performance improvements with high-frequency switch mode
- Performance comparison between both approaches
