Abstract: A serial-parallel converter protection system includes a controller, a drive, a first switching transistor, and a second switching transistor. An input terminal of a converter is connected to an output terminal of the converter through the first switching transistor. The output terminal of the converter is connected in parallel with the second switching transistor. When an output voltage of the converter is greater than a first threshold, the controller controls the first switching transistor to be turned off and controls the second switching transistor to be turned on. In some embodiments, when the output voltage of the converter is greater than the first threshold, the controller controls the first switching transistor to be turned off and controls the second switching transistor to be turned on, so that the converter is bypassed, thereby preventing a voltage and a current from impacting a component inside the converter.

Abstract: Contents of the next commands are considered as part of an arbitration between virtual functions (VFs). The device controller will hold the head of the submission queues (SQ) internally. The controller is able to do so by implementing a small first in first out (FIFO) per submission queue. The second arbiter and the main arbiter, which is responsible for the command scheduling, fetches the commands from the internal small FIFO. Using this technique, the second arbiter gains visibility of the next commands that participate in the arbitration since the next commands are held internally and not in host memory.

Abstract: A box-type substation, an energy storage power supply system, and a photovoltaic power generation system. The box-type substation includes a low-voltage cabinet, a high-voltage cabinet, a transformer, a first keychain, and a second keychain. When two circuit breakers in the low-voltage cabinet are in a switched-on state, each of the first keychain and the second keychain is locked at a corresponding circuit breaker. Therefore, when maintenance is performed on the transformer, the circuit breakers in the low-voltage cabinet are switched off first to remove the first keychain and the second keychain. Then, the first keychain and the second keychain are used together to switch off a disconnector in the high-voltage cabinet, and the first keychain and the second keychain are locked at the disconnector when the disconnector is in a switched-off state. Mechanical lock logic of the box-type substation is simple with high efficiency.

Abstract: Instead of handling resources with one generic method, the controller can use a static method or dynamic method to handle the resources. The controller communicates to the host as to the number of resources the controller has for keeping doorbell times. The controller will also communicate with the host how those resources are used. The static method focuses on creating dedicated submission queues (SQ), while the dynamic method provides a hint during the doorbell execution. The static method further focuses on improving priority, while the dynamic method focuses on canceling commands that have timed out. The static method and the dynamic method can be combined to further support the hosts requirements.

Abstract: Embodiments described herein aim to optimize the Erratic Program Detection (EPD) process by eliminating unnecessary operations and adjusting operations that are not optimized for the EPD process. For example, one optimization includes the EPD read operations being performed based on a read mode optimized for faster data retrieval. Further, another optimization includes a first read voltage ramping up at a rate that is faster than a ramp rate used to ramp up a read voltage during performance of a normal read operation. Another optimization also includes a read voltage kick operation between the EPD read operations being eliminated. Finally, another optimization includes parallelizing the scan operation with other ongoing operations.

Abstract: A data storage device has an inference engine that can infer a read threshold based on a non-linear function of inputs that reflect current memory and data conditions. The read threshold can be used in reading a wordline in the memory. Using a machine-learning-based approach to infer a read threshold can provide significant improvement in read threshold accuracy, which can reduce bit error rate and also improve latency, throughput, power consumption, and quality of service.

Abstract: Read commands and write commands are issued by a data storage device, but sometimes a read command can begin execution prior to the data for the write command having been written to the memory device (or HMB DRAM). In such a scenario, the data for the read command is not in the memory device, but rather, is in cache waiting to be written to the memory device in a write cache operation. In order to ensure the correct data is read, the cache write operation can be paused so that the data can be retrieved from cache rather than the memory device. Alternatively, a placeholder can be used for the read command until the write cache operation has occurred.
