Temperature control system and method thereof
A temperature control system and method are provided. The system includes a first channel, a second channel, a heating element, a DUT chamber, a converter, a first PID controller, and at least one switching regulator. The heating element is disposed downstream of the first and the second channels to heat the first air from the first channel or the second air from the second channel according to an input power so as to provide mixing air with a temperature into the DUT chamber. The converter converts an AC power to a DC power. The first PID controller provides a first input signal according to a first set point and an amount of power consumed by the heating element. The input power is adjusted by the switching regulator to drive the heating element according to the first input signal. Thus, the use of electrical power is more efficient.
