    Abstract: A bi-directional power converter, a control unit, a charging device and a method for transferring power between an EV and a power grid are provided. The bi-directional power converter includes an isolated DC-DC converter having a first stage converting a DC voltage into a high frequency AC voltage, a second stage capable of converting a high frequency AC voltage having an amplitude V2 into the DC voltage having an amplitude of V2 or 2V2, and converting the DC voltage into a multi-level high frequency AC voltage, and an intermediary stage electrically coupled to the first and the second stages, having a high frequency transformer of a turns ratio V1:V2.

    Abstract: This application discloses a common-mode voltage adjustment method and apparatus, and a control system, and relates to the field of electronic technologies. In an example method, a controller generates an injection instruction of a first common-mode voltage based on a first modulation scheme, generates an injection instruction of a second common-mode voltage based on a second modulation scheme, and generates an injection instruction of a third common-mode voltage based on the injection instruction of the first common-mode voltage and the injection instruction of the second common-mode voltage during a modulation scheme switching period. The injection instruction of the third common-mode voltage may be used to control a inverter circuit to output the third common-mode voltage.

    Abstract: A drive circuit having asymmetrical drivers. In an embodiment, a brushless DC motor may be driven by a drive circuit having three high-side MOSFETs and three low-side MOSFETs. A driver controller turns the MOSFETs on and off according to a drive algorithm such that phase currents are injected into motor coils to be driven. The high-side MOSFETs may be sized differently than the low-side MOSFETs. As such, when a MacDonald waveform (or similar drive algorithm) is used to drive the phases of the motor, less power may be required during disk spin-up because the MOSFETs that are on more (e.g., the low-side MOSFETs with a MacDonald waveform) may be sized larger than the MOSFETs that are on less (e.g., the high-side MOSFETs). In this manner, less power is dissipated in the larger size MOSFETs that are on more than the others.

    Abstract: A single-phase DC-AC converter generates an AC voltage with five levels at the output converter side by using four controlled power switches. The converter has a relationship between the number of levels per number of switches (nL/nS) of five to four. The converter reduces the number of semiconductor devices required to generate a high number of levels at the output converter side, requires only one DC source to generate an AC output, and operates with high efficiency.
