Abstract

The use of high-temperature superconducting pulsed power transformers (HTSPPT) for repetitive pulsed power supplies has been demonstrated. However, this type of inductive pulsed power supply (IPPS) has a problem that cannot be ignored, that is, it has more residual energy that is difficult to recover when facing inductive loads. In this paper, a residual energy recovery circuit unit is designed for this type of repetitive IPPS for inductive loads. With this circuit unit, the residual energy of the secondary inductors can be recovered and reused for the next discharging phase. To illustrate this circuit, simulations were carried out. The results show that the circuit can reduce the falling time of the load current pulse in the case of inductive load.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
