Inductive loads present particular challenges for DC-DC power modules at the instance of turn-off. In the following figure, the characteristics of an inductive load are shown for a simple inductor and series switch. Opening the switch breaks the current path from the module to the inductor very...
For a more dependable solution to the problem of generating a non-standard +15V/-4V asymmetric output voltage combination, we need to use a semi-regulated circuit: Hack #2: Regulate just one of the outputs Using an asymmetric output DC/DC converter such as theRxxP21509Dwith +15/-9V nomi...
TheQ Factoror QualityFactor measures how reliable an inductor is at doing itsjob in an electrical circuit. It evaluates the efficiency of the inductor at a specific frequency, rating its performance. A high Q Factor means the inductor is excellent at its job, ensuring the circuit works precisel...
To understand how aboost converterworks, let’s first understand how an inductor works. Recall that an inductor is a passive electronic component that can store electrical energy in the form of magnetic energy. We can use this property to control the output voltage of our circuit. Here is how...
There are several damping strategies to consider—first, a simplified series-damped filter circuit with a resistor in parallel with the inductor. The damping at the corner frequency is much better, but it comes at the cost of decreased high-frequency attenuation due to the addition of a zero ...
Whenever an inductor based load is involved in a DC circuit, incorporating a back EMF protection diode or a freewheeling diode becomes imperative in order to protect the BJT or the mosfet responsible for driving it. How to Calculate Parallel Diode ...
After C2 the signal flows down the yellow wire to the power tube's pin 5 (grid). Resistor R9 has a dual function. It adds input impedance to the power tube amplifier circuit and acts as the tube's 'grid leak' resistor which keeps the grid at 0 volts DC. ...
Note fromEquation 1that the voltage across an inductor is zero when the current is constant. Thus, An inductor acts like ashort circuit to DC. NOTE 2 // An important property of the inductor is its opposition to the change in current flowing through it. The current through an inductor can...
Do you know how this inductor will affect the impedance of a circuit? Impedance affects how signals propagate through the board, how power is transferred between components, and how signals bleed into unwanted areas of your PCB. There are a number of analyses you can use to determine o...
