Voltage is generated or induced in a transformer when there is a change in current flowing in the coil (or flux in the core). Meaning constant current (DC) no induced voltage.<br />2. Saturation of transistor. Usually, as the base current or voltage increases, the collector and emitter current increases. But there is a limit that any DH-gmhttps://www.blogger.com/profile/16906779443966743177noreply@blogger.comtag:blogger.com,1999:blog-8622007552114030374.post-14824257778416181242011-11-14T16:36:54.390-08:002011-11-14T16:36:54.390-08:00hi your projects are good, but where can i learn a...hi your projects are good, but where can i learn about the theory of this kind of converter.Ernesto Medinahttps://www.blogger.com/profile/17235287771150588363noreply@blogger.comtag:blogger.com,1999:blog-8622007552114030374.post-8232126639773385902011-11-02T06:22:02.104-07:002011-11-02T06:22:02.104-07:00The easiest way of converting your car voltage fro...The easiest way of converting your car voltage from 12V to 5V is using a 7805 regulator. Your 12V will be step down to 5V and can deliver up to 1500mA, more than enough of what you need. See the <a href="http://www.simple-electronics.com/2009/11/12v-to-5v-dc-converter-using-7805.html" rel="nofollow">12v to 5V</a> for more info.<br />If you need 5V supply with more than 5A current, I suggest see <DH-gmhttps://www.blogger.com/profile/16906779443966743177noreply@blogger.comtag:blogger.com,1999:blog-8622007552114030374.post-81037994859795023502011-11-02T03:33:54.777-07:002011-11-02T03:33:54.777-07:00hi,
