  • Patent number: 11967906
    Abstract: A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

  • Patent number: 11915994
    Abstract: A package structure is provided. The package structure includes a semiconductor die and a thermoelectric structure disposed on the semiconductor die. The thermoelectric structure includes P-type semiconductor blocks, N-type semiconductor blocks and metal pads. The P-type semiconductor blocks and the N-type semiconductor blocks are arranged in alternation with the metal pads connecting the P-type semiconductor blocks and the N-type semiconductor blocks. When a current flowing through one of the N-type semiconductor block, one of the metal pad, and one of the P-type semiconductor block in order, the metal pad between the N-type semiconductor block and the P-type semiconductor block forms a cold junction which absorbs heat generated by the semiconductor die.
