We examine the effect of the Initiative on Chinese cross‐border M&As. We find that the Initiative significantly increases the probability and the transaction amount of M&A deals in target countries. Moreover, the market reacts more positively to these deals. We find that the effect is entirely driven by state‐owned enterprises during our sample period and it is more pronounced in firms that are located on the more‐developed eastern coast of China. The evidence suggests that the announcement of the Belt and Road Initiative was followed by economically meaningful cross‐border M&A in targeted countries.}, journal={WORLD ECONOMY}, author={Zhang, Chi and Kandilov, Ivan and Walker, Mark}, year={2021}, month={Dec} }

The introduction of a non-stop direct flight between two locations in different countries allows for faster travel and a lower cost of acquiring information, potentially facilitating acquisitions abroad. We examine this channel by considering cross-border mergers and acquisitions (M&A) activity between China and the U.S. Our results suggest that direct flights matter most in target selection. Direct flights are more important for M&A activity where information asymmetry is greater and for first time acquirers in the market. We demonstrate that endogeneity is unlikely to drive the results.}, journal={JOURNAL OF CORPORATE FINANCE}, author={Zhang, Chi and Kandilov, Ivan T. and Walker, Mark D.}, year={2021}, month={Oct} }

The proposed converter comprises two stages: a non-isolated ac/dc stage that connects directly to the medium-voltage line, and an isolated dc/dc stage that provides 100-W output power at 24 V, with 10 kV isolation. The proposed modular ac/dc stage uses just one active semiconductor device per module, features an internal capacitor voltage balancing, and achieves power factor correction by employing predictive current control. High switching frequency operation of both converter stages enable a reduction in system size and weight when compared to traditional low-frequency transformer-based approach. The proposed converter is simulated and its operation is validated experimentally on a 100-W prototype.}, number={4}, journal={IEEE TRANSACTIONS ON INDUSTRY APPLICATIONS}, author={Won, Jehyuk and Jalali, Gholamreza and Liang, Xinyu and Zhang, Chi and Srdic, Srdjan and Lukic, Srdjan M.}, year={2019}, pages={4145–4156} }

Compared to the state-of-the-art TLB PFC controllers, where a two-cycle prediction and a detection of an operating region are necessary, the proposed controller achieves a low total harmonic distortion of the input current by using a single equation to predict the input current in all operating regions of the converter, in just one operating cycle. The average current control is achieved by sampling at the peak of the triangular carrier. The proposed PFC controller significantly reduces the distortion of the input ac current near the zero-crossing points, resulting in a low total harmonic distortion of the input current. The operation of the proposed controller was evaluated, and its stability and robustness to parameter changes was confirmed analytically. The controller operating principles were verified in simulations and validated by experiments on a medium-voltage 50-kW converter prototype.}, number={10}, journal={IEEE TRANSACTIONS ON POWER ELECTRONICS}, author={Liang, Xinyu and Zhang, Chi and Srdic, Srdjan and Lukic, Srdjan M.}, year={2018}, month={Oct}, pages={8948–8960} }

The proposed fully modular fast charger uses off-the-shelf Silicon Carbide (SiC) power devices to convert the rectified single-phase 2.4 kV medium-voltage input to variable dc output. The adopted input-series-output-parallel unidirectional topology enables converter scalability in both the input voltage and the output power. Using wide bandgap (WBG) power devices enables 9 times reduction in volume and 6 times reduction in weight, compared to the state-of-the-art fast chargers, while exceeding the efficiency of the state-of-the-art fast chargers by more than 1.5% Based on the system requirements, the appropriate converter topology was selected, its operation was simulated and validated by experiments on the developed fast charger prototype.}, booktitle={2016 ieee energy conversion congress and exposition (ecce)}, author={Srdic, S. and Liang, X.
