Weekly Progress
Today the Engineering Team conducted a presentation on the progress project and
show the block diagram each function in rice cooker working to the teacher.
The various tasks the Engineering Team were search for information on sensor
temperature, trig phase, microcontroller, power supply , as well as heater.
According to the research, The product was created for the purpose of control system
AC output voltage level. The principle of phase controls The AC power (AC 220V), sine wave
signal ( phase angle 360 degrees ) and frequency of 50 Hz. The principle of phase controls
Triac(Triac) triggered by the control gate of the Triac. It detonated at the gates and phase. The
Triac will affect the voltage output by the alternator. Signal from the called. Zero Crossing. As
a reference point in the phase of the excitation signal.
