GaN power startup offers HVAC module
Startup Quantum Power Transication Ltd已推出其第一个产品，这是一个基于两个适用于供暖，通风和空调（HVAC）系统的氮化碳晶体管的功率模块。
QPT founder and CEO Rob Gwynne said, “GaN transistors have always promised the best performance and efficiency over silicon MOSFETs and silicon-carbide, but they are notoriously difficult to drive at speed. We have developed an entirely new and unique topology for driving GaN transistors allowing them to switch at speeds of up to 20MHz, delivering major benefits in power consumption and efficiency.”
业务开发经理理查德·奥德（Richard Ord）补充说：“电动机驱动系统（EMD）消耗了全球45％的能源，但是它们在典型的运营速度下的效率可能低至50％。我们的解决方案可以解决整个运行速度的性能，并可以提高效率高达35％。”
QPT, founded in December 2019, has developed novel approaches by providing GaN transistor drivers with picosecond timing precision and digital control loops. This combined with converter topologies based on RF techniques enables low loss switching, the company claims. Algorithms support state-variable control with bandwidths of up to 20MHz for sophisticated four-quadrant operation and both non-resonant and resonant switching.
The qGaNDrive Module from QPT integrates their core topology with two GaN 650V transistors in a fully EMC-screened turn-key power module that measures 60mm by 30mm
The three-terminal device works with any motor driver up to 500W. The company estimates that when applied to a typical 15kW domestic heat pump could deliver a return in energy savings in one hundred days or less.
