Optimizations of AC/DC Converters for Powering 5G Network

The telecommunication industry is rapidly evolving towards providing faster services to accommodate the global surge in network demand. The next-generation (5G) network aims to increase the current network speed by more than twentyfold. This transition brings enormous benefits for the economy and society. A main challenge faced by network providers, however, is that the existing infrastructure cannot fulfill the new requirements of the 5G network. For example, the future 5G small cells need to be more powerful than the conventional 4G network architecture. Thus, further research and development are required in powering future 5G network. The research and development at Alpha Technologies Ltd. in Burnaby is currently focussed on developing new two-stage power converter for powering 5G small cells with power 3KW. The work involves layout of power converters optimized for electrical and thermal performance. In addition, the converter will be evaluated in terms of its EMI performance.
