Deformation of the half bridge converter principle of electric circuit diagram
For high input, high power output, generally USES the way of circuit as shown. In the circuit, switching devices V1, V2, V3 and V4 as a group, both in series and can reduce the single pipe pressure values. In the practical application circuit switch device in the V1, V2, V3 and V4 can adopt double pipe or in parallel, can solve the problem of large current output. Common transformer can improve the utilization efficiency of transformer, and has the ability to resist imbalance. In series of half bridge circuit, power transformation V1, V2 and V3, V4 each maximum withstand voltage value of the switch tube is only ucs 1 or Uc2 value, if C1 = C2, the ucs 1 = Uc2 = Uin / 2 value, therefore can choose to reduce the pressure switch tube. Another V1, V2, V3 and V4 manifold can be used in parallel work, increasing the capacity of the output current; T can work on the positive and negative direction for transformer, greatly improve the efficiency of the transformer. In view of the above advantages, the circuit has been more widely used, especially in the occasion of high input voltage and high power output, its application is becoming more common. (View)

Double is excitation converter principle of electric circuit diagram
When need larger output power, generally adopt the double normal shock type conversion circuit of voltage overlay, as shown. Circuit features: (1) two normal shock type conversion circuit in parallel, T1 and T2 inverting 180 o drive, a doubling of the power and output frequency doubled, ripple and dynamic response is improved; (2) the series S1, S2, S3, S4 series), switch tube pressure by half; (3) to cancel the feedback coil, V1, V2, VpV4 are can feed path, reduce the production technology of transformer and other requirements; (4) with dead zone limit, features two parts there is no common mode circuit conduction problem, and high reliability. Characteristic: normal shock: conduction type feeder to load, when the time L power supply to the load. Pressure: single pipe is excited, maximum voltage switch tube is 2 uin. Two pipe is shock: switch tube maximum voltage for Uin. : transformer utilization rate is not high (only using the first quadrant hysteresis loop), the production process to add on the feed can coil. Purpose: because the two pipe is shock parallel circuit has big output power, output pulse frequency doubling, easy to filter, switch tube pressure by half (about the input voltage Ui. , so widely used in high power conversion circuit, is considered to be high reliability at present, manufacturing is not the main circuit of a complex.

The basic composing of switch rectifier circuit diagram
Switch rectifier is mainly composed of four parts: input circuit, power transformer, rectifier, filter circuit and control circuit, as shown. Input circuit will ac input voltage rectifier filter into a relatively flat high-voltage dc voltage, the power converter converts it to the high frequency pulse voltage, then through rectifying filter circuit converts the high frequency pulse voltage steady dc voltage, output to the load. Control circuit of the role is to ensure the stability of the output dc voltage and is adjustable. (View)

High resistance distribution circuit diagram

Published:2014/2/17 23:29:00 Author: | Keyword: High resistance distribution circuit diagram,

As shown in figure for high resistance distribution circuit diagram. It with low resistance distribution in the load distribution is the significant difference between concatenated certain resistance current limiting resistor R1, general value for 5 times ~ l0 times of battery internal resistance. If a shunt short-circuit happened at this moment, the system voltage drop and recoil peak voltage is small, this is because the R1 limiting the short-circuit current, at the same time L x di/dt is lesser also. As shown is voltage variation between N and R. Selecting suitable R1 and Rr, can make the voltage change between N and R within the scope of the power system permitted error, the system of independent among load, mutually influence. Over the road purpose to enhance the reliability of communication system. In practice, can be developed the application of multilevel high resistance distribution. (View)
