Application of ies pulsed power generator for mushroom cultivation

A pulsed high voltage was applied to logs for mushroom cultivation to clarify an effect of pulse high-voltage on mushroom growth. Inductive energy storage system was employed to construct a pulsed power generator with compact size. Copper thin fuse was used as opening switch to interrupt large circuit current in short time. The fuse had the dimension of 0.03mm diameter and 6 cm length. The 14 kV voltage charged in primary energy storage capacitor was multiplied using secondary energy storage inductor. The output voltage of the pulsed power generator was 120 kV with 100 ns pulse width. This pulsed high-voltage was applied to fifteen of 90 cm length logs inoculated nameko fungus. After applying voltage to the logs, the logs were cultivated for a month. The experimental results show that the total weight of nameko mushrooms in case of pulsed high voltage applying was 6.3 kg and this value was nearly 1.5 times larger than 4.3 kg in case without high-voltage pulse application. The amount yields of nameko mushrooms of each logs increase with applying pulse high-voltage.
