This paper attempts to summarize 10 major contemporary challenges for power electronics and system technology (PEAS technology). Historical background is first reviewed together with most recent technological advances. Recent advances are then discussed in detail. A recent breakthrough in megawatt system design and design verification is highlighted. We then articulate the challenges that PEAS technology is facing contemporarily. They are: Powering smart buildings, smart factories, and smart infrastructure, Renewable energy integration and structured microgrids, EV drives and vehicle power systems, Ultra-fast and ultra-efficient chargers, Appliances - “White goods,” Server and data center power systems’ Wireless power transfer, Powering IoT and wireless sensor networks, Storage and “power dump,” and ATGC (All things grid connected), system integration, and dynamic control. These 10 areas present technical barriers for us to overcome and anticipated progress will help define the future of power electronics and its impact to the power and energy industry at large.

“…CMOS also holds another challenge for monolithic mains AC-DC converters: voltage compatibility, as integrated components often tolerate only a few volts. By adding extra circuit techniques, today's monolithic DC-DC converters tolerate input voltages up to 17 V [8]. Considering the mains of 100 to 240 V RMS , it is clear that other circuit techniques are required to realize the voltage compatibility between the mains and CMOS technologies.…”

“…A resistive voltage division with a resistor bank for multiple division factors can implement previous model of 'time dependent voltage division' but results in a poor efficiency [8]. To increase the efficiency, a converter with capacitive division of the 120 V RMS input (V AC,P − V AC,N ) and one switching capacitor C 3 , shown in Fig.…”

A fully integrated AC-DC power converter that faces a mains voltage of 120 V RMS , 60 Hz is presented. The converter achieves an increased operating range and efficiency due to a switching capacitor which relies on the principles of charge redistribution and the memory effect. As such, the converter mimics a variable voltage division to bridge the voltage gap between the high mains and low DC-output. Customized ACswitches and a high-voltage capacitor ensure the high voltage capability. The AC-DC power converter is designed in a 0.35 µm-CMOS technology and achieves an output power of 15.16 µW at peak efficiency of 80.7 % on an active area of 9.8 mm 2 .

“…The time dependent voltage division could be implemented with a resistor bank and would result in the behavior described previously. However, a power converter based on resistors would result in poor efficiency [6]. As a consequence, the proposed chip uses capacitors to divide the AC voltage into a lower voltage.…”

“…V MAX limits the maximum output voltage of the converter and links the capacitor values to the AC-input (6). Like V MIN , the ratio between C 2 and C 3 is also crucial for the performance of the power converter, as explained subsequently.…”

A fully integrated AC-DC power converter interfacing the 120 VRMS mains and fabricated in 0.35 µm-CMOS is presented. The converter uses a variable voltage division approach in order to step down the high input voltage while increasing the power density. The design includes customized AC-switches and a high-voltage capacitor and achieves an output power of 15.16 µW at an efficiency of 80.7 % on 9.8 mm 2 .
