Diodes - Bridge Rectifiers are a subclass of the diodes family and they offer a range of advantages, most notably their low cost and low complexity. The DB103STR application field and working principle is just one example of what this technology can offer.

The DB103STR is a diode bridge rectifier made as a completely encapsulated module with built-in surge protection. It has a unique feature compared to other rectifiers, being its high-side voltage sense: with this feature, the DB103STR can tailor the output voltage to the input voltage by means of the addition of a voltage regulator.

This bridge rectifier module can be configured to operate from either AC or DC inputs, and has a high efficiency, low heat output, and low input ripple current. It features an active-clamp voltage regulator that can tailor the output voltage to accommodate the input voltage. It can be used for a variety of applications, such as charging batteries, powering12V AC/DC electronics, or general purpose switching power supply.

The DB103STR’s working principle is that of a full-wave bridge rectifier, meaning it works by using four diodes to convert alternating current (AC) into direct current (DC). Input voltage is supplied to the positive and negative terminals of the bridge, and then one of the diodes allows the positive half of the AC cycle to flow in one direction, while the other three diodes allow the negative half of the AC cycle to flow in the opposite direction. The resulting DC voltage is then available at the output terminals, allowing the regulator to convert it into the desired voltage.

In addition, the active-clamp voltage regulator utilised by the DB103STR helps to keep the output voltage steady even if the input voltage fluctuates. It does this by intercepting the input voltage peaks before they reach the bridge, and then clamping them down to the desired voltage. This ensures that the output voltage remains within a specific range, and that the available power is not wasted.

The DB103STR also has a built-in surge protection feature, which helps to protect it against accidental electrical surges and short-circuits. This feature also prevents damage that can be caused by an excessive input voltage, helping to extend the life of the rectifier.

In conclusion, the DB103STR is an economical and easy-to-use rectifier module that offers high efficiency, low heat output, and low input ripple current. It is capable of converting both AC and DC voltages, and its active-clamp voltage regulator helps to maintain the output voltage within a specific range. Moreover, its surge protection feature helps to protect the module against accidental electrical surges and short-circuits.
