Abstract: A half-bridge power device includes a module substrate, the upper surface of which includes a first half-bridge area, a second half-bridge area, a first half-bridge lead-out area, and a second half-bridge lead-out area, which are separate, the first and second half-bridge lead-out areas being located at the ends of the module substrate. The first and second half-bridge power chips are connected to the first half-bridge area and the second half-bridge area, respectively. The first, second, and third power connector terminals are connected to the first and second half-bridge areas, and the first and second half-bridge power chips to form a power loop.

Abstract: Provided are a Cryptomeridiol synthase and a coding gene thereof. Also provided are a Cryptomeridiol synthase and a coding gene, a engineered yeast containing the Cryptomeridiol coding gene, and a use of same in plant breeding and biosynthesis. The cDNA full-length sequence of the Cryptomeridiol synthase gene in Tripterygium wilfordii is obtained by means of polymerase chain reaction cloning. Then, by means of synthetic biology, the engineered yeast containing the Cryptomeridiol synthase gene is constructed to realize the production of Cryptomeridiol in the yeast.
