Wave trap
WAVE TRAP : Power plants and substati**s are c**nected by high voltage power transmissi** lines which transmit power typically at 50 or 60 Hz. These lines are also used to carry communicati** and c**trol signals for the operati** of the grid (local equipment status, readings, alarms and switching signals). These signals which are of much lower voltage than the power, use high frequency carriers and wave trap filters are employed to separate the power and communicati** signals at every receiving end.

Full-wave Rectifier with Smoothing Capacitor
*********************************** The smoothing capacitor c**verts the full-wave rippled output of the rectifier into a smooth DC output voltage. Generally for DC power supply circuits the smoothing capacitor is an Aluminium Electrolytic type that has a capacitance value of 100uF or **** with repeated DC voltage pulses from the rectifier charging up the capacitor to peak voltage. However, their are two important parameters to c**sider when choosing a suitable smoothing capacitor and these are its Working Voltage, which must be higher than the no-load output value of the rectifier and its Capacitance Value, which determines the amount of ripple that will appear superimposed ** top of the DC voltage. Too low a value and the capacitor has little effect but if the smoothing capacitor is large enough (parallel capacitors can be used) and the load current is not too large, the output voltage will be almost as smooth as pure DC. As a general rule of thumb, we are looking to have a ripple voltage of less than 100mV peak to peak [URL="https://www.facebook.com/photo.php?fbid=568176759881998&set=a.272792822753728.73570.109596902406655&type=1&relevant_count=1"][IMG]https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-frc1/p480x480/387366_568176759881998_153797218_n.jpg[/IMG] [/URL] |
