“…5f ) and 250 mF V 2 (69.5 μW h), respectively. For the thousand-volts of 670-ACPECs, it demonstrates greater advantageous in a wide voltage range, comparing to some commercial AECs with similar capacitance (e.g., 2.2 μF/450 V, Tinkersphere, USA; 2.2 μF/450 V, Samwa, Korea; 2.2 μF/450 V, Jamicon, China (Taiwan); 2.2 μF/450 V, Rubycon, Japan; 1 μF/400 V, GANGHUI, China; 1 μF/450 V, Jamicon, Europe (Prague); 1μF/450 V, KELTRON, India), which can be expected to be applied in AC line filtering that requires wider operating voltage ranges, such as complementary component in the power converter 53 , 54 . All of the above parameters demonstrate the high-rate performance of integrated ACPECs device.…”

Filtering capacitors with wide operating voltage range are essential for smoothing ripples in line-powered system, which are still unsatisfactory due to low energy density and limited working voltage scopes. Herein, we report an aqueous hybrid electrochemical capacitor with areal specific energy density of 1.29 mF V2 cm−2 at 120 Hz, greater than common aqueous ones. Interestingly, it can be easily integrated at scale to show excellent flexibility, controllable and stable filtering performance, in which an integrated device (e.g., seven units in series) exhibits fluctuation of 96 mV, 10 times smaller than an aluminum electrolytic capacitor with similar capacitance. A record-high 1,000 V can also be achieved after integrating 670 units, exceeding those reported so far, and about 1.5 times of commercial bulk aluminum electrolytic capacitors (~700 V). This work opens up a new insight for promising applications in multiple electricity transmission systems that requiring high smoothness under harsh voltage.

“…As shown in Figure 7, the trench distance in the trench terminal structure is simulated biased, and the breakdown voltage is changed by changing the distance between trenches in the terminal structure [11] . As the trench spacing increases, the depletion line expands to both sides of the PN junction more slowly [12] , the potential line is more symmetrical [13] , the electric field strength is relieved [14] , and the breakdown voltage will increase [15] , as shown in Figure 8. The trench spacing was increased from 1.0um to 1.5um, and the BV was increased by about 7V, thus determining the large breakdown voltage of the terminal structure at 2um.…”

This paper mainly introduces the TDMOS (Trench Double Diffused MOSFET). Through the simulation of device process parameters, the influence of process parameters on device breakdown characteristics, transfer characteristics, and output characteristics are analyzed from seven aspects from the epitaxial layer thickness, resistivity, implant dose and energy of P body and NSD, trench depth, the spacing and depth of the trench in the terminal structure. Thus, the design standard with a breakdown voltage greater than 100V, a threshold voltage of about 3V, and a resistance lower than 124 mΩ·um2 is reached.
