stable working state. Next, we will analyze in detail the transition process of the switching power supply at the start time. In Figure 1-19, when the active switch is switched from power-on to power-off, the back-EMR generated by the secondary Coils of the switching power supply transformer is:In formula, Q is the charge volume stored by the capacitor, c1 and c2 are the undetermined coefficient, ω =, is the angle frequency, that is, the charge rate

devices, comparator, oscillator, pulse width modulation, reference voltage, and other circuits. This part of the circuit has been integrated, made into a variety of switching power supply integrated circuit. The control circuit is used to adjust the switching time ratio of the high-frequency switch component to achieve the goal of stable output voltage.2. Single-ended anti-excited switch power supplyThe typical circuit 3 of the single-ended anti-exciting switch power supply is shown in. The so-

DataBaseHandler class to complete its database work, and converts a document object to a required output type using a ing method. The ing method returns a string, because it is assumed that the output is composed of character data. In addition, you can also use a StringBuffer.SQLMapper requires an SQL query string, an output type set, and a DataBaseHandler for executing specific work. They are initialized using the set method and retrieved using the get method:If (getSQL ()! = Null) (GetSQL ().

Sqlmapper The Sqlmapper class uses a Databasehandler class to complete its database work and uses a mapping method to convert the document object to the desired output type. The mapping method returns a string because the output is assumed to be composed of character data. Alternatively, you can use a stringbuffer. Sqlmapper requires an SQL query string, an output type set, and a databasehandle

This factory class becomes the entry for creating a specific Transformer instance. Currently, the mainstream implementations are:Saxon 6.x: com. icl. saxon. TransformerFactoryIm

, resulting in damage to the line tube (there is a stage Philips display batch damage this inductor, but as if the line tube is not damaged, may be good circuit protection design). On the 4th case, first of all, the display of the output transformer technology requirements are higher than the color TV line output transformers, the probability of damage is very low, should not be determined to determine the damage of the package. From the large number

In the Buck-boost converter, when the duty ratio of the control signal of the driving switch is D, the relationship between the output and the input satisfies the v_o=d/(1-d) v_i.2. Overview of five isolated DC-to-DC topologies 2.1 Forward-excited converters The basic topological structure of the forward converter is shown in Figure 2.5. By placing the transformer between the switching tube and the diode of th

In the world of things, everybody can fly now... Last weekend, I was bored. I wrote a Java version of airplane hitting game .. I want to talk with you, but don't like it (there are already a lot of resources on the network) Current functions: 1. The enemy has two types of aircraft: small aircraft and Big BOSS aircraft (1 drop of blood for small aircraft; 10 drops of blood for BOSS. We only set one drop of blood for you to modify the blood parameter) 2. Pills: blue pills and Red Pills 3: blue pi

The activity is painful, but generally it will not exceed half of the deck, so it will not fall off, other symptoms are often not obvious, which can be seen in the case of cardification. Most of them are caused by the loss of blood. According to the theory of "liver primary tendon,

device is different from the 0 V level of the B point, this will lead to a large amount of current flowing from devices with high potential to devices with low potential. How can we solve this problem? The transformer (isolating transformer) device appears. It filters the differential signals sent by PHY with the difference mode coupled coil to enhance the signal, and is coupled to the other end of the con
