What is Electric Infrared Heating?
Why did we go with a DC Heating element?
Simple – In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. Every time this happens the efficiency is reduced!! We use DC to avoid this an increase overall efficiency – constant current equals greater consistent heat output overall.
DC is preferred over AC in our heating application due to its constant and unidirectional flow of electric charge. Many other modern electronic devices, including your computers, LED TVs, and smartphones, utilize DC power, as DC supply ensures a stable and constant voltage level.
DC Waveform
DC circuits have a unidirectional flow of current and like AC it is not changing the direction periodically.
Waveform of DC is a pure sine wave. As you can see, the voltage is constant with respect to time.
AC Waveform
AC can be represented by many waveforms like a triangular wave, square wave but the most common representative is a sine wave. It is represented by amplitude and time. Amplitude is the peak value of the current.
What does this mean? It means that we can count on most DC sources to provide a constant voltage over time.
In our world, this equates to constant heat output!!
