Customer ServiceCapacitors are an essential component of your HVAC''s electrical system. The job of a capacitor is to store up electricity, kind of like a rechargeable battery, so that it can supply a small burst of energy to the motor it''s connected to when needed. There are two basic kinds of capacitors found in an HVAC unit: the start capacitors and the run capacitors. The start capacitor provides the

The reason for this is because the PNP drives the output off the collector (in a configuration called common-emitter) and has a fairly high output impedance.

Customer ServiceOften, you can tame the circuit by adding a simple resistor-capacitor (R-C) snubber to "damp out the ringing." In this post, I''ll outline a seven-step procedure that can help take the guesswork out of selecting your snubber values. Ringing can occur in any switching converter where an inductance and a capacitance form an inductor-capacitor
Customer ServiceThe ringing makes sense to me because the op amp output initially overshoots, then when the capacitor approaches the target voltage it overcharges before output drops, and the op amp output falls low, and that
Customer ServiceRinging is always caused by an interaction between a capacitor and some inductance. Sometimes the inductance is a stray inductance from a trace or wire. When choosing decoupling capacitors its frequently mentioned that the lower ESR has a greater tendency to cause ringing so its advised to use medium/high ESR capacitors.

Customer ServiceThe ringing makes sense to me because the op amp output initially overshoots, then when the capacitor approaches the target voltage it overcharges before output drops, and the op amp output falls low, and that cycle repeats. The low filter cutoff is the reason for the ringing because of the longer delay times. Lower cutoff (e.g

Customer ServiceDue to its superior loss characteristics, polypropylene film capacitors are a device of choice in high-current, high-frequency applications such as induction heating and thyristor commutation, as well as applications where a stable, linear capacitance is desired and other capacitor types are unavailable or unfeasible for some reason.
Customer ServiceAlso changes in output capacitor has impact in the input capacitor too. It is important to place a good capacitor based on the data sheets recommended capacitance and ESR values. Ceramic capacitors using X5R or X7R dielectric is a good choice. This is because they have good temperature stability and good low voltage co-efficiency. Reference:

Customer ServiceWhat is a Capacitor and What does it do. A capacitor is an essential electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by a non-conductive material called a dielectric. When a voltage is applied across the plates, electric charge accumulates on them, creating an electric field between the plates.
Customer ServiceRinging is always caused by an interaction between a capacitor and some inductance. Sometimes the inductance is a stray inductance from a trace or wire. When choosing decoupling capacitors its frequently mentioned that the lower ESR has a greater tendency to cause ringing so its advised to use medium/high ESR capacitors.
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
As long as the current is present, feeding the capacitor, the voltage across the capacitor will continue to rise. A good analogy is if we had a pipe pouring water into a tank, with the tank's level continuing to rise. This process of depositing charge on the plates is referred to as charging the capacitor.

Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: i = Cdv dt (6.1.2.5) (6.1.2.5) i = C d v d t Where i i is the current flowing through the capacitor,
