Single Phase Diode Bridge Rectifiers KBPC, KBPC-W

Single Phase Diode Bridge Rectifiers KBPC, KBPC-W AS ENERGITM in monolithic design, used in DC and AC circuits with loads to 50A and reverse pulse voltages up to 1600V.

The diode bridges are housed in a standard industrial case making it easy to easy integrate of the device into existing equipment.

An alternating current is fed to the input "~" of the circuit. In each of the half - periods the input current passes only through two diodes.As a result, at the output "+" and "-" we get a current pulsing at twice the frequency of the input current.

The material of the converter housing is non-flammable heat-resistant plastic or electrically insulated metal. The inside of the housing is completely encapsulated with epoxy resin. The polarity of the bridge is indicated on the enclosure.

A filter is used to smooth out the resulting pulsating DC current, often a high-capacity capacitor. KBPC and KBPC-W diode bridges have a high pulse overload capacity and a fairly low forward voltage drop. A special mounting hole is provided in the housing of the diode bridges for screwing additional cooling (radiators, coolers).

Single Phase Diode Bridges KBPC, KBPC-W are used in various power equipment - rectifier for power supplies; input rectifier for variable frequency drives; rectifier for DC motor field supplies; battery charger rectifiers; single phase rectifiers for power supplies; non-controlled DC motor field supply; DC power supply, for transistorized AC motor controllers.

Our company provides a quality guarantee for diode bridges of 2 years from the date of purchase. When supplying diode bridges, if necessary, we provide technical passport and certificate of conformity.

The final price of diode bridges depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.

Design features of KBPC diode bridges:

The single-phase half-period converter is designed with a 4-diode Graetz circuit ("Graetz bridge") with negligible equivalent active internal resistance. The input (designated "Input" or tilde "~") of the diode bridge operating circuit is supplied with alternating current. In each of the half-periods the input current passes through only two diodes of the bridge. As a result, at the output (designated as "DC Output" or with "+" and "-" signs) we get a current pulsing with a frequency twice as high as the input frequency. To smooth the resulting pulsating DC current use a filter, most often a high-capacity capacitor, which is connected to the output. The operating frequency is 50/60 Hz.


In principle, there is no difference in the operation of the circuit in the placement of a separate composition of 4 diodes or a single component - a KBPC diode bridge. However, in the second case additional advantages are created:

– the diode bridge gives the same guaranteed characteristics of each diode, while individual parts from different batches of manufacture may have different parameters even if the same manufacturer is chosen;

– diodes placed in a single enclosure are exposed to the same heat, which means they operate in a favorable thermal regime, which prolongs their operation period;

– installing diodes in the circuit requires additional heat sink, this is solved by installing heat sinks or coolers, using a diode bridge instead of individual diodes need only one heat sink instead of 4 separate;

– the diode bridge is structurally more compact and takes up less space on the printed circuit board.

Материал the diode bridge enclosure can be of 2 types: non-flammable heat-resistant plastic polymer or electrically insulated metal. In each, the internal components are fully encapsulated with epoxy resin, which has a high level of flame resistance. The KBPC bridge enclosure has a central mounting hole for screw mounting the heatsink.

The terminals of KBPC diode rectifiers can be flat terminals with solder holes or wire terminals (marked with "W" in the marking). The polarity of the terminals is marked on the housing. The leads are mounted directly into the through-holes of the printed circuit board. Wires mounting — by soldering or "mom" type terminals.
