    Many simple DC power supplies regulate the voltage using either series or shunt regulators, but most apply a voltage reference using a shunt regulator such as a Zener diodeavalanche breakdown diodeor voltage regulator tube. One major disadvantage of the simple shunt zener regulator is that it continuously draws the maximum allowable current from the power supply. The ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage. Note 1: Tantalum capacitors are and always have been the most unreliable capacitors ever made. So, for the above circuit we can use the following basic equations for R1 and R The current-limiting capability also becomes a handicap when a CVT is used in an application with moderate to high inrush current, like motors, transformers or magnets.

    Current regulators are used for keeping the supplied current constant, irrespective of variations in load resistance or input voltage.These transformers use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output voltage with a varying input current or varying load.

    The purpose of a voltage regulator is to provide a constant output voltage regardless of the load resistance. In other words, an ideal regulator.Both types of rotating machine produce a rotating magnetic field that induces an alternating current in the coils in the stator.

    Linear current regulators provide a precise constant current starting from a varying input voltage source. They are ideal for replacing discrete-component.We can use this to sense if the LEDs get hot, and the current can be reduced to compensate.

    Current limiting, power limiting, thermal shutdown and input overvoltage protection (up to January Pentawatt® TO-3 (4 lead) 60 V) make the L virtually.Compare this to Figure 1, which only manages a ripple rejection of about 25dB.

    A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V-I.However, these are almost always relatively noisy, having considerable evidence of the switching frequency and its harmonics on the DC supply.

    The LT is a monolithic switching regulator that can generate constant-current/constant-voltage outputs in buck, boost or SEPIC topologies over a wide.Most importantly, they have no bad habits, and that's an important consideration for any design.

    It will not be repeated here. Once the regulator load current passes through a transistor, the circuit is called a 'series' regulator, because the active output.This is only a very basic form of protection, and while it works it's certainly not a high-tech solution to the problem.

    An unregulated power supply will also change its output voltage with load, so as the circuit draws power, the voltage falls.

    The purpose of D1 is as described above - it prevents a voltage applied to the regulator's output from causing damage.

    The operation of the circuit is the same as the previous one with the difference being that the current can be adjusted in circuit by turning the knob of the potentiometer to vary the resistance.

    Of course this makes sense, because you must have IC fabrication to create a workable bandgap reference.

    A Zener diode is used in the circuit probably as a no brainer as if you remember Zener diode is used for voltage regulation.

    Switched Mode Power Supply systems owe their origin back to the days when valve or tube car radios needed a large HT supply.

    Because the series element is either fully conducting, or switched off, it dissipates almost no power; this is what gives the switching design its efficiency.
