A monolithic integrated switched filter bank has been designed to realize the working center frequency tunable in S-band. The switched filter bank was designed using 8 eight-order step impedance resonators (SIR) band-pass filters and Microelectromechanical Systems(MEMS) switched circuit, combined with low temperature co-fired ceramic (LTCC) technology for monolithic integrated design. The monolithic...
The three-phase series-connected modular multilevel converter (SC-MMC) is presented as one option for high-voltage direct current (HVDC) tap to reduce the cost of an HVDC station. Compared with conventional three-phase parallel-connected MMC, the number of semiconductor switches in SC-MMC is reduced by one-third to withstand the same dc voltage. First, the paper studies the operating principle of...
This paper proposes an integrated power conversion system in electric vehicle using modular multilevel converter, whose modular structure could manage the integrated battery cells to simplify the traditional battery manage system (BMS) meanwhile provide the motor driving function and battery charging function without using additional hardware. The all-in topology could therefore maximize the capacity...
Binary Machines (BMs) are a generalization of Linear Feedback Shift Registers (LFSRs) in which a current state is a nonlinear function of the previous state. It is known how to construct a BM generating a given completely specified binary sequence. In this paper, we present an algorithm which can efficiently handle the case of incompletely specified sequences. Our experimental results show that it...
Mutation analysis is widely considered to be an exceptionally effective criterion for designing tests. It is also widely considered to be expensive in terms of the number of test requirements and in the amount of execution needed to create a good test suite. This paper posits that simply deleting statements, implemented with the statement deletion (SDL) mutation operators in Mothra, is enough to get...
A potential application of BCI is the way of prosthesis control, while the traditional ways are not appropriate for those who got the high SCI (Spinal Cord Injury). In this paper, considering the practicality of BCI based prosthesis control, especially the avoidance of appended devices, the spontaneous EEG of motor imagery was used as the control signals. The motor imagery is limited in pattern variety,...
Electrical Impedance Tomography is applied to acquire the impedance characteristic, which is correlative with the physiological and pathological status of a body, and reconstruct the images of impedance distribution. Current injection with voltage measurement phantom is widely adopted in the application of biomedical detection. Voltage controlled current source (VCCS) develops an important part and...
This paper presents a theoretical study with experimental validation carried out on a DC-DC SEPIC converter operating in continuous conduction mode (CCM). Two dynamic modeling techniques are adopted and various aspects of the converter's operating modes are analyzed. Simulations of transient and frequency responses are verified with experimental results. A PI control law is used to validate responses...
