Energy storage capacitance is necessary part of pulse power generator. Generally, it is difficult to match the equivalent capacitance in high voltage side and energy storage capacitance in low voltage side of the pulse transformer. Resultantly, it requires high flow capability of switch device. In this paper, three methods are presented to solve this problem based on reasons of overcurrent. The results of simulation and experiments show that the efficiency of generator was higher with the method of thyristor and inductance in reverse parallel, and this method would be the most effective resolution.

By describing the environmental requirements for food storage, puts forward the green air conditioning system to create a low-temperature environment for food of these creatures such as ice storage air-conditioning, ground source heat pumps, solar cooling and so on. Combined the related system diagram or schematic in the context of promoting green and healthy, pointed out the future direction of development of the low-temperature grain storage.
