I have problem with the spike that happen in high frequency transformer. first picture show waveform with transformer and the second waveform show without transformer(connect with resistance).
I think it's related with leakage inductance.
can "extern" be after a function?, most of the example i see before the function:
#include "hello_world_objects.h"
void Start_screen(); extern;
void main() {
Start_TP();
Start_screen();
while (1) {
Check_TP();
}
}
this example i got from mikroe dspic example..
thank you
why in no load, the output only show the rectangular waveform. Is it to be pure sine wave after we applied LC filter?
i already got nice sine wave with pure resistive load.
thank you
I'm try to run mosfet with high frequency..30 khz..10 duty cycle. i got turn off switching in mickro second but when i read data sheet is about nano second. Is it normal?, or is anybody have idea to reduce this turn off switching

actually i try to shifting TBL_POINTER_NEW into 8 bit( since i got 256=1 0000 0000). So, it should get 1 right. But even, i change into TBL_POINTER_NEW>>=8 or i delete TBL_POINTER_NEW>>8 line, it still show 256 as answer. But when i try to implement this code with pic16f684(but with small sine...
I have problem when debug this code using mikroC.........
unsigned char sin_table[158]={0,3,6,9,12,15,18,21,24,27,30,
33,36,39,42,45,48,51,54,57,60,63,66,69,72,75,78,81,84,87,90,

hi guys,
i have problem with my output at secondary of high frequency transformer. It just show a spike only. I need a rectangular wave. Currently i'm using 20kHz frequency. Anybody can help to explain what happen in this cct. Thank you.
