A highly compact continuous-time transimpedance low-pass filter (TILPF) topology is proposed that achieves a low input impedance and a 2nd-order transfer function in a single stage. This is suitable to perform current-to-voltage conversion with a built-in filtering characteristic in a passive mixer based wireless receiver. A 4th-order Butterworth prototype is designed with a cascade of the proposed...
This paper provides a methodology for overall system level design of a high-power density inverter to be used for EV/HEV traction drive applications. The system design is guided to accommodate off-the-shelf SiC power modules in a planar architecture that ensures proper electrical, thermal, and mechanical performances. Bi-directional interleaved DC-DC boost structure and a three-phase voltage source...
Partial discharge (PD) detection is an important method to detect the defects in high-voltage bushings. Existing PD detection methods for bushings still have some problems related to the sensitivity and the anti-interference capacity. In this paper, an advanced method for the detection of PD in capacitor bushings is proposed to overcome the disadvantages of the conventional PD detection methods. The...
We propose a switched-capacitor radio-frequency (RF) front end achieving an equivalent high-order, tunable, highly linear RF filtering to improve the out-of-band (OB) blocker tolerance. RF input impedance matching, $N$-path filtering, high-order discrete-time infinite-impulse response (IIR) filtering, and down-conversion are implemented using only switches and capacitors in a 0.1–0.7 GHz prototype...
This paper proposes a new discrete-time complex bandpass (DT CBP) filter topology in charge domain, only using switches, capacitors, input transconductors and non-overlapping 2-phase clock scheme. The proposed DT filter features better power-efficiency, reduced complexity and easier process-scaling compared to the conventional topologies. It has an inherent anti-aliasing sinc characteristic due to...
Currently, the modular multilevel converters (MMCs) based high voltage direct current (HVDC) transmission system have been widely applied due to its better characteristics, such as the stringent modular structure and good line-side behavior. This paper studies the conducted common mode electromagnetic interference (EMI) in MMC based HVDC system. As a matter of fact, interference sources are very complicated...
A 0.1–0.7GHz switched-capacitor RF front end features tunable center frequency and programmable filter order as well as very high tolerance for out-of-band (OB) blockers. RF input impedance matching, N-path filtering, down-conversion, and high order IIR filtering are implemented using highly linear switches and capacitors only. The 3.24mm2 40nm CMOS front-end prototype consumes 38.5–76.5mA, achieves...
Light emitting diodes (LEDs) are likely to be used for general lighting applications due to their high efficiency and longer life. This paper presents the concept of applying large voltage ripple for energy storage into the Boost-Flyback Single-Stage PFC converter for the elimination of the electrical capacitor. Following proposed design procedure, the single stage PFC circuit with small energy storage...
A novel hybrid five-level DC-DC converter is proposed, which utilized two series connection bidirectional switch and two flying capacitors to provided middle electrical levels. With proper controlling, the volume of output inductance can be reducing to 1/8 compared with traditional full bridge DC-DC converter. The principle of operation and the dc characteristics of the new converter are analyzed...
