Vicor PI3741 DC-DC Power Conversion Module Makes Travel Electric Bikes Go Farther

American power supply manufacturer Vicor recently announced that its PI3741 DC-DC power conversion Module has been successfully assembled in the Tritek Power travel electric bicycle, which effectively improves the battery power supply and reduces the heat dissipation of the battery pack, enabling the travel electric bicycle to travel. Longer mileage and more reliability.

As a leading supplier of spare batteries for travel electric bicycles, Tritek Power, located in Shenzhen, China, specializes in the production of spare battery packs for travel electric bicycles, with small size, high efficiency, high reliability and strong electromagnetic compatibility. characteristic. According to reports, Tyco Power’s travel electric bicycle spare battery pack weighs only a little more than 2 pounds and can provide a driving range of nearly 30 kilometers.

The motor of the travel electric bicycle is driven by direct current. Although the lithium-ion battery outputs direct current, the output voltage of the battery is not very stable with the change of battery power and the external environment, so a DC-DC converter is needed to provide the motor with stable voltage. An excellent DC-DC converter must not only have a stable output, but also its conversion efficiency should be high enough to ensure that the battery power is fully utilized. The overall efficiency of Tyco Power’s battery pack can be as high as 90%, which is 5%-10% higher than that of similar products. Among them, the Vicor PI3741 DC-DC power conversion module is indispensable.

An excellent DC-DC converter can not only improve the utilization rate of battery power, but also reduce the heat dissipation of the battery pack, so that the heat dissipation requirements of the battery pack will be reduced, and the use of heat sinks will be avoided, thereby further reducing the battery pack’s heat dissipation. size and weight.

The most prominent feature of the PI3741 DC-DC power conversion module of Vicor Corporation in the United States used by Tyco Power is high efficiency. Its input voltage range is 30V-42V, and its output voltage is 42V, which is very suitable for output conversion of travel electric bicycle backup battery packs . The thermal management design of the battery pack becomes simpler due to high efficiency and less heat dissipation. The reliability of the battery pack is also improved due to the use of fewer components.

Vicor’s proprietary Zero Voltage Switching (ZVS) technology enables the PI3741 to have excellent high conversion efficiency. ZVS technology allows zero voltage during switching and reduces silicon losses during switching. Vicor integrates the ZVS topology into the chip, which achieves high integration under high conversion efficiency, reduces the number of external components, reduces the solution size, and improves product reliability.

The PI3741 module provided by Vicor to Tyco Power is packaged in the form of LGIZ, which is more convenient for heat dissipation. The size is only 10 mm x 14 mm x 2.5 mm, and the conversion efficiency can be as high as 97%, which is two percentage points higher than competing products. In addition, PI3741 has very low EMI radiation, which provides a strong guarantee for customers’ end products to meet the strict quality certification in Europe and the United States.
