3 is a circuit diagram of a water purification unit according to an embodiment of the present invention. The water purification unit can include an MPC circuit. MPC is a pulse compression circuit consisting of a very short pulse generation circuit centering on a short-term energy accumulation capacitor and a semiconductor switch for performing high-speed discharge, and a boosting transformer, a saturable inductor and a capacitor It consists of two parts.

In Figure 3, C 0 is the first stage energy accumulator capacitor, SL 0 is a saturable inductor, PT 1, PT 2 is a pulse transformer for boosting, C 1, C 2 for reducing the turn-on losses of the semiconductor switch (IGBT) is medium Pulse generating capacitors SL 1 and SL 2 are charging inductors of C 1 and C 2 . SL 0 , SL 1 , and SL 2 are saturated by applying a DC bias to the auxiliary winding, and exhibit low impedance characteristics in one direction, but have blocking characteristics in the opposite direction. The operation of the circuit of Fig. 1 until C 0 is charged and voltage is applied to the load will be described below.

First, after charging C 0 with DC power, turn on the GTO. SL this time 0 to the saturation voltage of C 0 0 SL is applied to the current rarely flows. As a result, the turn-on loss of the GTO is suppressed and the heat generation of the GTO is suppressed, so that the high-permittivity operation becomes possible.

Next, when SL 0 saturates, a discharge current flows from C 0 to the IGBT, and the voltage of C 0 is boosted at PT 1 to charge C 1 .

Then, when after completion of the 1 C charge, SL 1 is saturated, that C 2 is charged with the voltage of C 1 is the step-up in the PT 2. By reducing the secondary winding of PT 2 by dividing the step-up by two stages, the inductance component in this loop becomes small during saturation.

The time for conducting the water treatment can be set differently according to the degree of water pollution. For example, the water pollution zone above a predetermined standard may be set to be relatively long so that the water treatment time is relatively long, and the water pollution zone below a predetermined standard may be set so that the water treatment time is relatively short so as to correspond thereto.

Next, when the water treatment at a specific point is finished, it is moved to the next water treatment point and it is confirmed whether the moved point is the last water treatment point (S500). If it is the last water treatment point, move the point to the initial waiting position after water treatment. If the moved point is not the last water treatment point 550, the process of repeating the process of water treatment after the point is moved to the next water treatment point.

If an obstacle is detected during the movement to the next water treatment point, the water treatment at that point is skipped and then moved to the next water treatment point.
