Yes i understand that it is current dependent as when the load current decreases below critical current value it will be in DCM and there's an equation for DCM. When i add voltage mode control, am i right to say that no matter DCM or CCM the output voltage will follow my reference voltage and...
I understand that there's 2 mode of operations. Discontinuous current and continuous current. The critical resistance is Rb and if the resistive load is higher than the critical resistance the system is in DCM.
That's theoretical and for open loop buck converter. What happens when i add a...
Hi all. I am trying to build a buck converter with feedback loop. The output is suppose to be a 5V and i am using a type 3 compensator. The input is 12V, however i am unable to obtain a 5V and worst there's ripple at the output when using psim. My compensator doesn't seem to be working as it...
I wonder why my micro controller is not able to delay when our input is linked to a motion sensor and output to led. Based on our program, the led is supposed to turn on for 15 mins but it is unable to do so. Instead, it is following the output of the motion sensor but nt the output of the port...
So is CFL and/or incandesent lamp of high frequency? So LED is good in what way and fluorescent is good in what way? What if the light is to be use in an open area. Anyway i am connecting the lighting to a PV module. So LED will be much wiser right? As some energy will be lost from the inverter...
May i know am i able to use multimeter to show the different power consumption of LED and fluorescent. And if i am not wrong LED is much better than fluorescent.
well i have a free pic 18f4550 so yeah. use fan dimmer huh. how about setting the light to turn on at a preset time? can this be achieve by using pis 18f4550?
PIC 18F4550
May i ask am i able to set something like a timer in which it will turn something on at predetermined time. As i would like to switch on light at night. Further more i would also like to use PIC 18F4550 to dim light when no one walk through at sudden time. And the light will...
