The method is mainly to add harmonic extraction and suppression functions to a four-quadrant converter control algorithm, without using additional hardware control circuit and device, has high adaptability and flexibility, can achieve the purpose of harmonic suppression, and also reduces design costs.

Title: Storage box and electronic device

Abstract: A storage box (10) includes a body (100), a cover (200), and a first magnetic unit (300). The body (100) is provided with a receiving space (101). The cover (200) is rotatably attached to the body (100) and is configured to rotate relative to the body (100) to drive the storage box (10) between an open state and a closed state. In the closed state, the cover (200) covers the receiving space (101). In the open state, the receiving space (101) is exposed. The first magnetic unit (300) includes a first magnetic member (310) attached to the body (100) and a first attracting member (320) attached to the cover (200). Opening the storage box (10) from the closed state causes the first attracting member (320) to move closer to the first magnetic member (310). Magnetic force between the first magnetic member (310) and the first attracting member (320) drives the cover (200) to rotate away from the closed state and into the open state.
