Title: Common mode current controller for inverter
Inventor: GAO YONGBING
IPC: H02S40/32
Filed: 2021-07-13
Abstract: A common mode current controller (600) of an inverter includes switches (604, 606) and an impedance correction circuit (602). One end of the impedance correction circuit (602) is grounded, and the other end is connected to one end of each of the switches (604, 606). The other end of each of the switches (604, 606) is connected to one of a positive terminal and a negative terminal of a direct current busbar capacitor. When a midpoint-to-ground voltage (BUSN) of the direct current busbar capacitor exceeds a threshold range, the switches (604, 606) are closed to adjust impedance matching between a positive terminal-to-ground equivalent impedance (RES positive ) of the direct current busbar capacitor and a negative terminal-to-ground equivalent impedance (RES negative ) of the direct current busbar capacitor, so that the inverter can pre-control a magnitude of a common mode current generated when the inverter is grid-tied, thereby reducing impact of a common mode current generated at a grid-tied instant.

Title: Wideband amplifier linearization techniques
Inventor: WU KUN-LONG
IPC: H03F1/30
Filed: 2021-08-19
Abstract: A wideband power amplifier (PA) linearization technique is proposed. A current interpolation technique is proposed to linearize power amplifiers over a wide bandwidth. The wideband power amplifier linearization technique employs a novel transconductance Gm linearizer using a current interpolation technique that achieves improvement in the third order intermodulation over wide bandwidth for a sub-micron CMOS differential power amplifier. By using a small amount of compensating bias into an opposite phase differential pair, linearization over wide bandwidth is achieved and can be optimized by adjusting the compensating bias.
