The research directions are:
· Integrated power electronics controller design
· The integrated power electronics controller can significantly improve the power electronics system performances and is easy to be implemented by others (without knowledge and save programming time)compared with conventional DSP controller. Moreover, the integrated power electronics controller is possible to replace the digital controller in the power compensator products. This research work focuses on programmable gain signal conditioning circuit, analog-to-digital (A/D) conversion, and pulse-width-modulation (PWM) generator. Up to now, there is no such three-phase power electronics controller IC in the market.
· Power management IC design
· Fully-integrated high efficiency, wide input range, wide load current range, small output ripple, and fast transient response power management circuits, including inductor-based and switched-capacitor DC-DC converters, low dropout regulators, etc. are of great interest.
· Wireless power transfer
· Wireless power transfer (WPT) has a wide range of applications including (arranged from low to high power levels) radio frequency identification (RFID), internet-of-things (IoT), implantable medical devices (IMDs), real-time wireless power for non-contact memory devices and wafer-level testing, and also wireless chargers for portable/wearable devices and electric vehicles (EVs). It is evident that the utilization of WPT technologies is on the critical point of exponential Growth.
The research line aimed at the investigation of the advantages of using microelectronics through signal processing and intelligence in order to improve the performance of energy processing power electronics systems, which is related with software control and hardware IC implementation. Power management and wireless power transfer are our research focuses.
