The unit 8 includes a transformer 8] and a 敕, , :: ", the city valve has a main 〇, and the positive electrode. 81 with 811 connected to the city's secondary line (7) 2 and -_ ratio, the main coil becomes =: electricity, § _ circle 812 is connected to the whole, because (4) ^ is converted into a lower voltage, the power is reduced to The half pressure 'supplure', the whole: 1 such as the use of the 81 81 81 81 81 81 81 81 81 81 81 81 81 ΡΚ 可选 ΡΚ 17 ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ ΡΚ The voltage regulator capacitor C2 is swapped out - the secondary coil 812 of the DC voltage regulator 81 is still a voltage: here. 'Because the voltage RMS of the transformer 812 is preferably /2 with the pre-coil. The ratio of the direct voltage is as described above, compared with the conventional ocean current power converter, which uses only a simple mechanical structure and sends out "following f, but does not have any conversion" and thus the efficiency of the neon and the stability of the supply = According to the invention, the adjustable DC link voltage circuit 4 can be used according to the step-down and the mode between the battery 3 and the voltage stabilizing capacitor C2. The energy can be increased (4) bidirectional _, which can improve the power generation efficiency and the service life of the pool, and can also select a battery field with a smaller capacity. Therefore, the flexibility of the design can be further increased.
