Troubleshooting a Power Supply Circuit

S Bharadwaj Reddy
Troubleshooting is the application of logical thinking combined with a thorough knowledge of circuit or system operation to identify and correct a malfunction. A systematic approach to troubleshooting consists of three steps:

Capacitor Filter Operation

S Bharadwaj Reddy
Capacitor filter.  Fig. shows a typical capacitor filter circuit.  It consists of a capacitor C placed across the rectifier output in parallel with load RL. The pulsating direct voltage of the

Power Supply Circuit Fault Analysis

S Bharadwaj Reddy
In some cases, after isolating a fault to a particular circuit, it may be necessary to isolate the problem to a single component in the circuit. In this event, you have

Basics of Voltage Regulator

S Bharadwaj Reddy
Voltage Regulator The 78XX series of linear voltage regulators provide positive fixed output voltages for a range of values. The last two digits in the part number indicate the output

Capacitor Filter Working Principle

S Bharadwaj Reddy
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of
