Abstract: An insulation resistance detection circuit is coupled to a positive end and a negative end of a DC power source, and is used to detect a positive insulation resistance between the positive end and a ground point and detect a negative insulation resistance between the negative end and the ground point. A detection unit sets a first estimated resistance and a second estimated resistance, and acquires a first voltage based on turning on the switch and acquires a second voltage based on turning off the switch. The detection unit calculates a third voltage and a fourth voltage according to the first estimated resistance and the second estimated resistance so as to detect the positive insulation resistance and the negative insulation resistance when the third voltage is equal to the first voltage and the fourth voltage is equal to the second voltage.

Abstract: A charging system includes a power input part, an inverter, a DC bus, at least one charging device, a first bidirectional energy storage module, a second bidirectional energy storage module and an intelligent controller. The charging device includes a DC/DC converter and a charging gun. A first bidirectional DC/DC converter of the first bidirectional energy storage module receives and converts the DC power from the inverter for charging a first battery, or converts a first storage electric energy of the first battery for the charging device. A second bidirectional DC/DC converter of the second bidirectional energy storage module receives and converts the electric energy outputted by the DC/DC converter of the charging device for charging a second battery, or converts a second storage electric energy of the second battery for the charging device.

Abstract: A fan includes a frame, an impeller and a motor. The impeller includes a hub, a plurality of blades, first air-guiding plates and second air-guiding plates. The hub has a tapered shape. A width of the hub gradually increases along a direction from a top portion of the hub to a bottom portion of the hub. The hub has at least an air vent. The blades are disposed around an outer periphery of the hub. The first air-guiding plates and the second air-guiding plates are disposed around an inner periphery of the hub. The first air-guiding plates are arranged between two of the second air-guiding plates in staggered. The second air-guiding plates are arranged between two of the first air-guiding plates in staggered. The first air-guiding plates and the second air-guiding plates have different thicknesses, heights or shapes.

Abstract: A power converter includes a power factor correction (PFC) circuit and a controller. The controller acquires a switching frequency based on an instantaneous value of the input voltage, and acquires an upper limit frequency and a lower limit frequency based on an effective value of an input current. When the controller determines that the effective value is greater than a medium load threshold, an operation mode of the PFC circuit is switched from a critical conduction mode or a triangular current mode to a continuous conduction mode based on the switching frequency being less than the lower limit frequency, and to limit the switching frequency to the lower limit frequency. Furthermore, the controller adjusts the lower limit frequency between a first lower limit frequency and a second lower limit frequency based on the increase or decrease of the effective value.
