摘要： The present invention relates to the technical field of motor control, in particular to a motor control method, a motor, a vehicle, a storage medium, and a computer. The motor control method implements the movement of a modulation interval of a voltage waveform by introducing online adjustment of a power factor angle, thereby ensuring that the action of a switching tube does not occur in a drive system under a large current, improving the driving efficiency of the system, and ensuring the universality of this solution.

摘要： This invention relates to the field of high-voltage ceramic capacitors and discloses a new high-voltage ceramic bus supporting capacitor for automotive inverter, the bus supporting capacitor includes a positive busbar, a negative busbar, and several high-voltage ceramic capacitors; the positive busbar integrates a busbar positive network and several positive busbar interface ports are arranged on one side of the positive network; the negative busbar integrates a busbar negative network and several negative busbar interface ports are arranged on one side of the negative busbar; the negative busbar interface ports are staggered with the positive busbar interface ports and are both used to connect half-bridge SiC module or multilayer composite busbar; all the high-voltage ceramic capacitors are evenly spaced between the positive busbar and the negative busbar, and positive terminals of the high-voltage ceramic capacitors are connected to the positive busbar and join the busbar positive network, and negative terminals are connected to the negative busbar and join the busbar negative network; there is a heat dissipation fluid between adjacent high-voltage ceramic capacitors. This invention can effectively increase space utilization and eliminate the need to consider safety distance and creepage distance between solder pads.
