Abstract: A soft-switching power converter includes a main switch, an energy-releasing switch, and an inductive coupled unit. The main switch is a controllable switch. The energy-releasing switch is coupled to the main switch. The inductive coupled unit is coupled to the main switch and the energy-releasing switch. The inductive coupled unit includes a first inductance, a second inductance coupled to the first inductance, and an auxiliary switch unit. The auxiliary switch unit is coupled to the second inductance to form a closed loop. The main switch and the energy-releasing switch are alternately turned on and turned off. The auxiliary switch unit is controlled to start turning on before the main switch is turned on so as to provide at least one current path.

Abstract: An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.

Abstract: The present invention relates to nucleic acid sequences that encode hepatitis C viruses (HCV) of genotype 6a that are useful in the fundamental research of HCV as well as in the search of antivirals and vaccines against HCV. In particular, the present invention relates to nucleic acid sequences that comprises HCVs, which are capable of expressing said virus when transfected into cells and are capable of replication or infectivity in cultured cells.

Abstract: A pulse modulation method for adjusting pulse signals according to a working voltage of a load, the method includes the following steps. The working voltage of the load is detected by a feedback terminal of a PWM controller. Whether the load is a light load or a heavy load is determined, if the load is a light load, a pulse skipping mode is entered; the voltage output to the load is detected by the feedback terminal. Whether the voltage output to the load is normal is determined, if the voltage output to the load is low, the pulse skipping mode is stayed for a number of clock cycles; the voltage output to the load is detected to determine whether the voltage is normal. If the voltage output to the load is still low, the pulse skipping mode is jumped out and a normal working mode is entered.
