Abstract: A multi-phase LLC power converter comprises a plurality of LLC phases each including a resonant tank and a switching stage. The resonant tank includes a resonant inductor, a resonant capacitor, and a parallel inductance. The switching stage switches an input power at an operating frequency to apply a switched power to the resonant tank, with the switched power approximating an alternating current (AC) waveform having a switching frequency. A secondary-side controller varies the switching frequency to control an output voltage of the multi-phase LLC power converter. A primary-side controller measures primary-side currents, calculates an initial switch-controlled capacitor (SCC) conduction phase angle for each of the LLC phases, and operates an SCC switch in accordance with an SCC conduction phase angle to adjust the capacitance of the resonant capacitor of an LLC phase to cause each of the LLC phases to have equal resonant frequencies.

Abstract: A non-puncturing microwave ablation antenna, including an irradiator located at a front end of the antenna and an irradiator cover sleeved on the irradiator, where a front end of the irradiator cover is blunt. Because the front end of the irradiator cover is designed to be blunt, the special non-puncturing appearance of the irradiator cover enables the antenna to freely penetrate inside the lung tissue without puncturing blood vessels and bronchi in the lungs. In addition, blood vessels of tumor existing in the Ground-Glass Opacity (GGO) would not be damaged by the blunt head and bleed, thereby reducing a rate of surgery failure caused by that a lesion cannot be identified because of bleeding inside the lung, and in addition, avoiding a possibility that tumor cells spread through a puncturing passage or bleeding blood vessels.

In the presence of the IPTG, the recombinant virus has similar characteristics to a wild-type virus; and in the absence of the IPTG, the expression of the D1133L protein is inhibited.
