How the ripple voltage is generated

Ripple voltage, English ripple voltage, also known as ripple voltage. As the image of the ripple, the voltage on the wire is marked like a wave of waves.

The curious question is how the ripple is produced. Control what, from the source and control of the two parts to start.

Google has come to the following passage:

Ripple is often random, but sometimes other components in the circuit can cause this noise to occur. For example, a relay or motor switching can often times cause a sudden fluctuation in the voltage. Much like disturbing, the water level in a pond. The more current of the other component uses, the bigger the ripple effect. "From an engineer's blog"

Ripple is usually a relatively random value, but many of the other components in the circuit cause these noises (the ripple is actually noise, and all we want is noise). For example, relays and motors in circuits often cause a mutation in the current. What happens next is like throwing a pebble into a pond. At the same time, the greater the current required by other components in the circuit, the more ripple is caused.

While all of these benefits was noteworthy, perhaps the greatest motivation for using the current Doubler rectifier is the Reduced ripple current seen by the output capacitors. In some sense, the current Doubler rectifier can be thought of as a two-phase, interleaved synchronous buck. As shown in Figure 2, maximum ripple current cancellation for a two-phase synchronous buck occurs when each phase is opera Ting at percent duty cycle. However, because the volt-seconds applied to the transformer primary must is equal for each half of the power transfer Cyc Le, the current doubler are limited to a maximum duty cycle of the percent per phase, whereas the two-phase synchronous buck Can operate at greater than percent duty cycle per
Phase. "From Ti"

The maximum ripple suppression for the two-phase buck converter occurs when the phase angle is buck converter an-off cycle 50%.

Ripple current was the AC component of an applied source (often a switched-mode power supply) whose frequency could be consta NT or varying. Certain types of capacitors, such as electrolytic tantalum capacitors, usually has a rating for maximum ripple current (b Oth in frequency and magnitude). This ripple current can cause damaging heat to being generated within the capacitor due to the current flow across resistive Imperfections in the materials used within the capacitor, more commonly referred to as equivalent series resistance (ESR). For example electrolytic Tantalum capacitors is limited by ripple current and generally has the highest ESR ratings in The capacitor family, while ceramic capacitors generally has no ripple current limitation and has some of the lowest ESR Ratings.
