Design of a Bridge Rectifier

Bridge rectifiers change AC voltage into DC voltage.
They are used in a wide variety of electronics and most often found in AC powered devices,
modern home telephones, simple plug-in power supplies and even in high horsepower motor controllers.
Many modern devices have benefited from these solid-state silicon semiconductor devices,
as they have replaced the failure-prone metal oxide rectifiers used many years ago.

Function

Bridge rectifiers can be either in a 'half wave' or a 'full wave' configuration.
Electrolytic filter capacitors are commonly added to smooth the rectification pulsations.
The device can also be used for assuring that DC (battery) power happens in a fixed way
even if the battery is connected improperly. In modern telephones,
they assure proper connectivity and electrical isolation to the incoming phone lines.
Even if the phone wires are miswired, the phone will still work properly.

Kingtronics are a producer of bridge rectifier with many years. We have got UL Certificate for our bridge rectifier.

Here are our Bridge rectifier items: DB107, MB10S, KBL4005,KBU610, KBPC2510,KBPC2510W, KBPC35005-KBPC3510, KBPC3510W........etc..

Description

HC-49S crystals share the same base outline as the industry standard HC49 crystal. The crystal uses at AT-cut strip crystal with an hermetically sealed can. HC-49S crystals provide a low cost source of system clock frequency.

Multilayer ceramic capacitors with silver/palladium (Ag/Pd)terminations have often been used in medical applications where non-magnetic components are required, for example in MRI equipment. The use of conventional nickel barrier terminations is not suitable due to nickel exhibiting magnetic properties.

However, RoHS requirements have dictated the use of lead-free solders, and the composition of these solders has resulted in an increase in soldering temperatures. This has caused solder leaching problems for the Ag/Pd termination, and meant alternative terminations have had to be found.

This copper barrier termination is offered with selected nonmagnetic C0G/NP0, High Q and X7R dielectrics, providing a fully non-magnetic component.

Tantalum electrolytic capacitors now available have mainly three categories of the solid sintered, foil winded and wet sintered type.

tantalum chip capacitors are playing a dominant role in the markets along with the development of technology, miniaturization is in the ascendant and the ratio of chip type to all types of capacitors is growing, Among them, the sintered solid accounts for over 95% of the current total production, dominated by non-hermetical epoxy-encapsulated tantalum capacitor.

Solid tantalum capacitors have advantages of excellent electrical performance, wide working temperature range, good volume efficiency and various forms of encapsulation.

Kingtronics sell good quality under our brand Kingtronics. All our products are RoHS compliant,pls see cross reference:

Is it possible to obtain more pulses than twice the number of phases in a rectifier circuit? The answer to this question is yes: especially in polyphase circuits. Through the creative use of transformers, sets of full-wave rectifiers may be paralleled in such a way that more than six pulses of DC are produced for three phases of AC. A 30o phase shift is introduced from primary to secondary of a three-phase transformer when the winding configurations are not of the same type. In other words, a transformer connected either Y-Δ or Δ-Y will exhibit this 30o phase shift, while a transformer connected Y-Y or Δ-Δ will not. This phenomenon may be exploited by having one transformer connected Y-Y feed a bridge rectifier, and have another transformer connected Y-Δ feed a second bridge rectifier, then parallel the DC outputs of both rectifiers. Since the ripple voltage waveforms of the two rectifiers' outputs are phase-shifted 30o from one another, their superposition results in less ripple than either rectifier output considered separately: 12 pulses per 360o instead of just six

Select a higher voltage rated part (30% to 70%) than the maximum line voltage. In the case of low impedance circuits, the tantalum capacitor is likely to be stressed by current surges. In circuits which undergo rapid charge/discharge, a protective resistor of 1.0 ohm per applied volt is recommended. If this is impossible, a voltage-derating factor of up to 70% is recommended. A combination of tantalum capacitors can be connected in series to increase working voltage of the equivalent capacitor. In many power supply topologies where the di/dt through the capacitor is limited, such as most implementations of buck (current mode), forward converter and flyback, the requirement for series resistance is decreased to 0.1 ohm per applied volt. This level of resistance is used as a basis for the series resistance variable in a 1%/1000 hours 60% confidence level reference. This is what steady state life tests are based on. Certain test circuits such as ICT are likely to subject the capacitor to large voltage and current transients, which will not be seen in normal use. This should be taken into account when considering the capacitors rated voltage.

The tantalum capacitor is a highly reliable type of solid capacitor orelectrolytic capacitor.

Surface mount tantalum capacitors are increasingly being used in circuit designs because of their volumetric efficiency, basic reliability and process compatibility.

Tantalum capacitors are manufactured from a powder of relatively pure tantalum metal. The typical particle size is between 2 and 10 μm.

Kingtronics manufacture and sell capacitors for many years. We can produce military standard goods for dipped tantalum capacitors.
