Embodiment Construction

[0138] The present invention can provide a power converter 100 with improved lifetime and reliability, while reducing size and audible noise. like figure 1 and figure 2 The power converter 100 of the present invention depicted above can be seen as improving the lifetime of energy storage systems (ESS for short) (also known as energy storage elements, ESE for short) by minimizing the current flowing through them. The power converter 100 described in this application may be dedicated to energy storage systems having a high nominal voltage, which may be meant to include between 750 VDC and 950 VDC. Specifically, the present invention can provide a bidirectional power converter 100 because the power converter 100 can be used as a boost converter 100 or a buck converter 100 .

[0139] The power converter 100 may comprise at least one primary switching arrangement 130 , a secondary switching arrangement 170 and a resonance unit 150 connecting the primary switching arrangement 130...

Abstract

The invention relates to a bidirectional power converter (100) for converting an input voltage into an output voltage. The bidirectional power converter (100) may include a primary switching unit having a primary switching frequency and a secondary switching unit having a secondary switching frequency: the primary switching frequency being lower than the secondary switching frequency.

Description

technical field [0001] The invention relates to a power converter for converting input power into output power, a step-up process and / or a step-down process for converting input power into output power. More specifically, the present invention addresses, but is not limited to, electric traction systems capable of driving an electric motor and recovering kinetic energy towards an embedded energy storage system. Background technique [0002] As the technology of batteries and supercapacitors has improved over the past few decades, electric vehicles have become an attractive solution with economical realities. And, thanks to the commitment of several countries around the world to comply with the COP21 Act, traditional all-petrol vehicles could be jettisoned and replaced by electric solutions. One of the first applications will be public transportation, such as, for example, bus and tram systems. In these applications, high power is required to supply the traction unit. [00...
