VFP-H series variable frequency power supply is manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation.
Comparing to traditional frequency inverter power supply, our inverter power supply removes the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC inverter power supply could give stable AC output with prefect output precision.
Because, our new technology does not need transformer for conversion and isolation, the power supply size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
BMW shared car entered Chengdu and took the lead in investing in 100 i3 operations
BMW is set to launch its first official car-sharing service in China next month, with Chengdu as the starting point. This marks a significant step for the German automaker as it expands its mobility solutions into the Chinese market. The service will feature the BMW i3 electric vehicle, and it's part of a broader strategy to explore new business models beyond traditional car sales.
The ReachNow car-sharing initiative, which was first introduced in the U.S. in 2016, previously tested in Beijing before expanding to Chengdu. Unlike the earlier pilot in Beijing, where users had to return the vehicles to specific locations, the new Chengdu project allows users to park the cars anywhere, offering greater flexibility and convenience.
This move comes as BMW looks to adapt to the growing challenges of urban traffic congestion and environmental concerns in China. With increasing restrictions on private car ownership, the company aims to provide sustainable and innovative mobility options that align with modern consumer needs.
According to Thiemo Schalk, a BMW executive, "Future growth will not come from just selling cars, but from offering new services." The company is investing heavily in this model, with 100 i3s deployed in Chengdu as part of the initiative.
In Europe, the DriveNow service has already reached over 1 million users and achieved profitability. In the U.S., ReachNow operates in three cities with around 1,400 BMW and Mini vehicles. BMW plans to bring similar high-quality offerings to the Chinese market, where shared electric vehicles have been gaining popularity, though most are based on low-cost domestic models like those from SAIC and Shouqi Group.
The success of shared mobility in China has also been influenced by the widespread use of shared bicycles. However, issues such as improper parking and uneven distribution remain challenges. BMW’s approach aims to address these by offering a more user-friendly and flexible system.
With this new initiative, BMW is positioning itself as a leader in the evolving mobility landscape, aiming to redefine how people access and use vehicles in urban environments.
