It really needs to be stressed that this is a fit for duty analysis as in, "I will determine if I should employ this guy for a physical job by seeing if he can do 40 push-ups." They didn't normalize for any of the cardiac risk factors (smoking, cholesterol, diabetes, blood press...
If a small output current is commanded, the duty cycle is reduced by the PWM controller, but if the duty cycle becomes smaller than 20 %, the linear voltage regulator starts to reduce the input voltage for the buck regulator. Below a duty cycle of about 7 % the output is controlled ...
It is a pilgrimage that feels like one’s civic duty. We need to be reminded of the pain that was felt that awful day. Our pain has subsided but for those who lost family members, it never goes away. Walking through the museum one never knows what might touch the heart or cause you...
