problem with inverter in proteus
When I try to simulation the following design in proteus, the software always shows that timestep too small,trouble with node....(the node about the switches).When i delete the switches circuit,the simulation can work well. Help me ,please!
Re: SPWM inverter using PIC16f877A
I hope the following will be helpful.
my code for init
void CCP_start()
{
sin_am=0.2000;//sin函数的幅值
crut_ie=1;//电流慢保护允许
sin_up=1;//正负半周SIN函数
sin_num=0;//脉宽周期调整计数器
TMR2ON=0;
TMR1CS=0;//同步模式
T1SYNC=0;//内部指令周期
T1CKPS1=T1CKPS0=0;
TMR1H=0XF9...
