to Know how to connect the bridge rectifier KBPC3510, we must first Understand the positive and negative full-wave rectifier bridge Circuits. It is more convenient to understand the wiring of the Rectifier bridge in the circuit. the bridge circuit is made up of four Rectifier diodes, and the AC voltage is input at two connection points Where the positive and negative poles are connected. the positive Voltage output end is where the negative electrode is connected to the Negative electrode, and the positive electrode is connected to the Positive electrode. this is the circuit characteristic of the rectifier Bridge rectifier circuit.
the two pins marked AC on the side are Connected to the AC power supply (transformer secondary). the pin marked + on the side is the rectified positive output, and the pin marked-on the other side is the negative output.
Anatomizing the commonly used Low-power rectifier bridge stacks will reveal that the full-wave Rectifier bridge stacks use plastic packaging structure (most of the Low-power rectifier bridge stacks use this packaging form). the four Main heating elements in the bridge, the diodes, are divided into two Groups and placed on the copper plates of the DC output pins. There are Two connecting copper plates between the DC output pin copper plates, Which are respectively connected to the input pins (AC input wires), Forming a full-wave rectifier bridge stack with four external connection Pins that we see on the appearance.
Because this series of Rectifier bridge stacks all use plastic packaging structure, the above-mentioned diodes, lead copper plates, connecting copper plates and Connecting wires are filled with epoxy resin, which is an insulating and thermally conductive skeleton filling material. however, the thermal Conductivity of epoxy resins is relatively low (typically 0.35 ° C W / m and high at 2.5 ° C W / m), so the junction-to-case thermal resistance of the rectifier bridge stack is generally large (usually 1.0 ~ 10 ° C / W).
