  • Publication number: 20240195293
    Abstract: A circuit for preventing power imbalance of a resonance-type power converter is proposed. The circuit may include a rectifier converting input alternating current (AC) into direct current (DC) and frequency-controlled first and second resonant converter modules configured to receive an output voltage of the rectifier divided into two stages. The circuit may further include a controller outputting a first frequency command for controlling a frequency of a pulse width modulation (PWM) signal supplied to a switching element of a first switching unit of the first resonant converter module. The circuit may further include a frequency compensator compensating for the first frequency command and then outputting a second frequency command for controlling a frequency of a PWM signal supplied to a switching element of a second switching unit of the second resonant converter module, so as to eliminate power imbalance between the first and second resonant converter modules.

  • Patent number: 11971764
    Abstract: A storage device includes a solid state drive (SSD), a field programmable gate array (FPGA), a power sensor and a global controller. The SSD stores data and receives power through a power rail connected to a host device. The FPGA processes data read from the SSD or data to be stored in the SSD and receives power through the power rail. The power sensor is connected to the power rail and generates a measured power value corresponding to a total power consumed by the SSD and the FPGA by measuring the total power. The global controller determines one of the SSD and the FPGA as a priority component operating with a fixed performance and determines the other of the SSD and the FPGA as a non-priority component operating with a variable performance in a priority mode based on power control information provided from the host device.
