The first and second elastic supporting members connects to the housing by the elastic frame. By virtue of the bended structure of the elastic frame, the first and the second elastic supporting members are arranged interlaced along the vibration direction, which greatly reduces the height of the vibration motor. | 2020-05-14 |
20200153325 | MOTOR CONTROL APPARATUS EQUIPPED WITH BOOSTING UNIT - A motor control apparatus includes: a converter configured to convert AC voltage input from an AC power supply side into DC voltage, and then output the DC voltage to a DC side; an inverter configured to convert DC voltage input from the DC side into AC voltage for driving a motor, and then output the AC voltage; and a boosting unit configured to step up DC voltage input to the inverter from the DC side, according to a deviation between a speed command to the motor and speed information acquired from the motor. | 2020-05-14 |
20200153326 | DISC-TYPE SPEED REGULATION MAGNETIC COUPLER BASED ON BEVEL GEAR DRIVE - A disc-type speed regulation magnetic coupler based on bevel gear drive is provided, consisting of a driving disc assembly and a driven disc assembly, wherein a speed regulation device is mounted on the driving disc assembly. | 2020-05-14 |
20200153327 | FLYBACK POWER CONVERTER AND ZVS CONTROL CIRCUIT AND CONTROL METHOD THEREOF - A ZVS (zero voltage switching) control circuit for controlling a flyback power converter includes: a primary side controller circuit for generating a switching signal, to control a primary side switch; and a secondary side controller circuit for generating a synchronous rectifier (SR) control signal for controlling a synchronous rectifier switch. The SR control signal includes an SR-control pulse and a ZVS pulse. The SR-control pulse controls the synchronous rectifier switch to perform secondary side synchronous rectification. The secondary side controller circuit determines a trigger timing point of the ZVS pulse according to a waveform characteristic of a ringing signal, to control the synchronous rectifier switch to be ON for a predetermined period, thereby achieving zero voltage switching of the primary side switch. The primary side or the secondary side controller circuit includes a jitter controller for performing jitter control on the ZVS pulse. | 2020-05-14 |
