Latest Patents

One of his latest patents is a high-density power supply. This invention includes a shell, a fan, a PFC module, a DC-DC module, and a main board. The design features a first air passage and a second air passage arranged side by side, with the fan positioned either on the inner or outer side of the shell. The PFC module contains a PFC inductor located in the first air passage, facing directly towards the fan. The DC-DC module, also situated in the first air passage, comprises at least one DC-DC conversion circuit, which includes a first PCB, a transformer magnetic core, transformer winding, and power components. The main board is housed within the shell, with the PFC inductor and the DC-DC conversion circuit electrically connected to it.

Another notable patent is the totem pole power factor correction circuit. This circuit features a detection module and a control unit. The detection module includes a first detection resistor and a first detection circuit. When a voltage difference is detected across the first detection resistor, an output voltage is generated. The control unit assesses the operating state of the circuit based on this output voltage. If the circuit is functioning normally, the control unit manages the on/off states of the corresponding switches according to the output voltage.
