  • Patent number: 10250126
    Abstract: The present invention discloses a method applied in a controller unit of a feedback circuit for controlling a resonant converter. When the operation mode of the resonant converter turns from no load (or light load) to full load (or heave load), the controller unit is configured by the method of the present invention to control a power switch unit in the resonant converter to switch ON and OFF according to an operation frequency of full load (such as 100 KHz), in the case of the fact that an instantaneous drop of the output voltage and a variation of the output current of the resonant converter are over predicted. As a result, the instantaneous drop of the output voltage is largely reduced. Therefore, this method is able to make the resonant converter provide the output voltage stably during the switch between the no-load operation mode and the full-load operation mode.

  • Patent number: 7779186
    Abstract: A master-slave card system includes a master card and a plurality of slave cards connected in serial. The master card sends a command with a station-number information to the slave cards. A selected slave card designated by the station-number information sends back a response message, where the response message includes an initial packet, a plurality of data packets and a CRC check packet. The master card sends a next command to a next slave cards after the master cards identifies a correct initial packet. When the initial packet is not correct, the master card halts sending the next command until the received signal is already stopped for a predetermined silence time. The master card drops all the data packets if the CRC check packet associated with the data packet is not correct.

  • Patent number: 7612326
    Abstract: An angle-calculation apparatus for three-phase optical encoder receives three-phase sinusoidal signals 120 degree phase from the optical encoder and obtains angle information for a motor rotor. The angle-calculation apparatus includes an A/D converter, a digital signal processor (DSP), a phase digitalizer and a digital counter. The A/D converter converts three-phase analog signals of the optical encoder into three-phase digital signals. The phase digitalizer converts the three-phase analog signals into digital phase signals. The digital counter generates a counting value based on the digital phase signals. The DSP performs an inverse trigonometric function calculation on a relatively linear region of the three-phase digital signals to obtain the angle information. The DSP obtains the rotation turn number and rotation direction of the motor rotor according to the counting value.

  • Patent number: 7547875
    Abstract: A high-precision absolute type encoder apparatus includes a controller electrically connected to an incremental type encoder and generating a control signal to the incremental type encoder, a comparator electrically connected to outputs of the incremental type encoder and generating first pulse signals, a latch unit electrically connected to outputs of the comparator and generating second pulse signals by latching the generating first pulse signals. When power failure occurs, the controller generates the control signal as successive pulses with predetermined period to drive the latch unit and the incremental type encoder. Therefore, the controller knows angular information of the incremental type encoder by counting the second pulse signals. The absolute angular information can be obtained by combining the angular information and an initial position after power failure.

  • Patent number: 7460974
    Abstract: A multiple-point smoothing method for motor-speed estimation. The output of an encoder is over-sampled to obtain over-sampled position differences according to an over-sampling factor M. The over-sampled position differences are averaged to obtain an initial speed estimation. The initial speed estimation is low-pass filtered to obtain a final speed estimation. The final speed estimation is sent to a speed controller to control the speed of a motor. Alternatively, in a composite multiple-point smoothing scheme, the initial speed estimations based on two over-sampling factors are obtained. One of the initial speed estimations is selected based on an average of the two estimations, and the selected initial speed estimation is further processed to obtain a final speed estimation. The method of the present invention can reduce ripple in estimated speed of motor when the motor is operated at high speed.
