Unlike conventional PFC designs, bridgeless topologies eliminate the need for a diode bridge, reducing conduction losses and improving overall performance. By adopting these techniques, you can achieve a better power factor and lower total harmonic distortion (THD), which are critical for maintaining a stable DC power supply.

Recent studies highlight the advantages of bridgeless PFC designs. For example, a bridgeless boost PFC topology demonstrated superior power factor correction and reduced THD compared to traditional methods. An experimental prototype achieved a system efficiency of 97.3% at full load, showcasing its effectiveness in telecom applications. Additionally, integrated PFC designs further enhance performance by reducing supply current THD and improving power factor, making them ideal for telecom rectifier modules.

Tip: When designing the telecom rectifier circuit, consider bridgeless PFC techniques to maximize efficiency and minimize energy losses.
