Re: H-Bridge inverter design
Hi, I am building a 3 phase bridge circuit for a BLDC motor. I would like to know which is the better way and why?
1) Use 3 N-MOSFET for low side and 3 P-MOSFET for high side with the high side mosfet driven by a NPN transistor or
2) Use N-mosfet for high and low...
Re: PWM for atmega8
i want to vary the pwm to vary the speed of the motor
the frequency should be 8Khz
the voltage should change from 0V to 5V
Yeah...need to change the pwm for a single count.
Re: PWM for atmega8
hey yeah...i have done some coding. But I want a varying pwm. How do i implement that?
This is what ive got so far...
#include <avr/io.h>
#include <util/delay.h>
int main(void)
{
uint8_t delay;
uint16_t pwm;
long count;
DDRB=0xFF;// PortB as output
TCCR1A |=...
Hello.
Im trying to create PWM to control the speed of a brushless DC motor on
atmega8.
The pwm will be connected to the gates of the 3-half bridges.
So i will need to use 2 channels from timer1 and 1 channel from timer2.
Could anyone help me with the coding? because im a beginner in...
