By Matt Rosenberg. A nations economy can be divided into various sectors to define the proportion of the population engaged in the activity sector. This categorization is seen as a continuum of distance from the natural environment.he packaging and processing of the raw material associated with this sector is also considered to be part of this sector. In developed and developing countries, a decreasing proportion of workers are involved in the primary sector.
RC SNUBBERS (SMPS) Snubbers are energy-absorbing circuits used to suppress the voltage spikes caused by the circuit's. inductance when a switch, electrical or mechanical, opens. The most common snubber circuit is a. capacitor and resistor connected in series across the switch (transistor).
The snubber capacitor is calculated from the peak current and the target rise time. The capacitance is given by the equation: When the snubber network is installed in the application the voltage transients on the terminals of the L6203 are greatly reduced, as shown in figure 2.The drawback of a snubber network of this type is that a current spike will flow into the transistor when it is switched on as the capacitor is discharged.The theoretical peak value of this spike is given by the equation : The following graphs are of operating voltages with snubber network and bypass capacitor.he snubber capacitor is calculated from the peak current and the target rise time. The capacitance is given by the equation: When the snubber network is installed in the application the voltage transients on the terminals of the L6203 are greatly reduced, as shown in figure 2.
