FILTERS While the output of a rectifier is a pulsating dc, most electronic circuits require a substantially pure dc for proper operation. This type of output is provided by single or multisection filter circuits placed between the output of the rectifier and the load. There are four basic types of filter circuits: Simple capacitor filter […]

Ac component in an lc choke-input filter , resistor-capacitor (rc) filters , failure analysis of the resistor-capacitor (rc) filter and voltage regulation ,
Ac component in an LC choke-input filter. Let’s go a step further and redraw the filter circuit so that you can see the voltage divider action. Refer to view A of figure 4-24. Remember, the 165 volts peak 60 hertz provided by the rectifier consists of both an ac and a dc component. This first […]

Photodiode Figure 3-31. – Photodiode. A second optoelectronic device that conducts current when exposed to light is the PHOTOTRANSISTOR. A phototransistor, however, is much more sensitive to light and produces more output current for a given light intensity that does a photodiode. Figure 3-32 shows one type of phototransistor, which is made by placing a […]
