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.

The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.
