Abstract: A power conversion system with ripple injection includes an AC-DC conversion unit, a voltage regulation unit, at least one DC-DC conversion unit, at least one load, and a first control unit. The voltage regulation unit provides a DC link and receives one portion of an input power as an energy storage power. Each DC-DC conversion unit receives the other portion of the input power as an output power. The at least one load correspondingly receives the output power for being supplied power. The first control unit is coupled to the DC link, the at least one DC-DC conversion unit, and the at least one load. The first control unit controls the at least one DC-DC conversion unit to adjust a magnitude of a ripple of the output power to perform a ripple injection operation according to a magnitude of a ripple of the input power.

Abstract: A centrifugal fan is disclosed and includes a housing, a fan wheel, a first throat portion and a second throat portion. The housing includes a lower cover connected to an upper cover through a peripheral wall to form an accommodation space and an outlet. The upper cover includes an inlet communicated with the outlet. The fan wheel is disposed on the lower cover and accommodated in the accommodation space. The fan wheel is rotated along a rotation direction. The first throat portion is disposed adjacent to a lateral end of the outlet and protrudes from the peripheral wall toward the accommodation space. The second throat portion is disposed adjacent to another lateral end of the outlet, and protrudes from the peripheral wall toward the accommodation space. When the fan wheel is rotated along the rotational direction, an airflow is guided from the first throat portion to the second throat portion.

The gear-plate-output, a reducer-output shaft and a reducer-fixed shaft of the reducer are disposed in parallel and sleeved on the pedal shaft concentrically. The motor drives the gear-plate-output shaft to rotate. The first sensor is disposed on the reducer-fixed shaft for sensing a first torque of the reducer-output shaft acting on the reducer-fixed shaft. The reducer-fixed shaft is connected to the housing. A frameset-fastening component protrudes outwardly from the housing, and is configured to fix the power module on the frameset. The second sensor is disposed on the frameset-fastening component for sensing a second torque of the power module acting on the frameset. The driving controller controls the motor in accordance with the second torque and the first torque.
