The current detector 207 detects the current value of the output signal output from the linear amplifier 206 to the synthesizer 210, and outputs a signal having a voltage corresponding to the detection result to the power output unit 208.

The second switching amplifier 216 amplifies the signal inputted thereto and outputs the amplified signal to the low-pass filter 209.

The first switching amplifier 215 and the second switching amplifier 216 will be described in detail below. The first switching amplifier 215 includes an NMOS drive transistor 218 and a diode 219.

The anode of the diode 219 is grounded, and the cathode is connected to the source of the driving transistor 218 and the low-pass filter 209. Since the first switching amplifier 215 has the above configuration, when a positive voltage equal to or higher than the threshold voltage is input to the gate of the driving transistor 118, the current from the DC power supply 217 (on the drain side of the driving transistor 218) becomes the current of the low-pass filter 209 (on the drain side of the driving transistor 118 of the driving transistor 218).

When a voltage equal to or higher than a set threshold voltage is input to the gate of the driving transistor 218, the time differential value of the current flowing through the low-pass filter 209 is positive, and otherwise, the time differential value of the current flowing through the first low-pass filter 209 is negative or zero. That is, when a voltage equal to or higher than a predetermined threshold voltage is input to the gate of the driving transistor 218, the first switching amplifier 215 increases the output current. Thus, the first switching amplifier 215 outputs a current according to the output signal from the first comparator 212. Note that the predetermined threshold voltage in the driving transistor 218 is a voltage between the voltage of the high-level signal and the voltage of the low-level signal output from the first comparator 212. Further, the first switching amplifier 215 outputs a current having a positive current value.

A DC power supply 217 is connected to the drain of the drive transistor 218 and the cathode of the diode 220. The first low-pass filter 222 of the low-pass filter 209 attenuates the high-frequency component of the output signal of the first switching amplifier 215 and outputs the attenuated high-frequency component. The second low-pass filter 223 attenuates the high-frequency component of the output signal of the second switching amplifier 216 and outputs the attenuated signal. The output signals of the first low-pass filter 222 and the second low-pass filter 223 are combined in a combiner, and output to the power supply terminal 211.

The utility model discloses owing to be provided with watertight cabin and matrix control circuit that are the matrix form and arrange, consequently, when connection structure non-rigid, thereby the balance that controls the flotation tank through the intake condition and the inflow of control watertight cabin is convenient for make the flotation tank sink steadily. For example, when the buoyancy tank is high at the left and low at the right, the water inflow at the right side is fast, so that the switch in the watertight compartment electric control valve passage at the right side can be turned off or the opening time is shortened, the water inflow is suspended or the water inflow is reduced, the switch in the watertight compartment electric control valve passage at the left side is turned on, the opening amount is increased, the water inflow is accelerated, when the buoyancy tank is parallel to the horizontal plane, the switches in the watertight compartment electric control valve passages at the two sides are both turned on, and the water flows in simultaneously until the buoyancy tank sinks to the set position. In order to stabilize the buoyancy tank, the opening amount of the electric control valve is sequentially increased along a certain direction according to the inclination angle of the buoyancy tank, and if the buoyancy tank is high at the left and low at the right, the opening time of the electric control valve is sequentially reduced from left to right. When the buoyancy tank needs to be withdrawn, gas is injected into the air chamber of the watertight cabin, for example, air is injected to discharge water in the watertight cabin, and meanwhile, the buoyancy of the buoyancy tank is increased, so that the buoyancy tank floats up and is withdrawn, resources are saved, and the water area cannot be polluted by the abandoned buoyancy tank. Because the utility model designs a matrix switch control circuit, can control the intake and the drainage of the watertight cabin of arbitrary row and column very conveniently to can control the sunken degree of depth of flotation tank very conveniently.

Above-mentioned each embodiment only is used for explaining the utility model discloses, wherein the structure of each part, set up position and connected mode etc. all can change to some extent, all are in the utility model discloses equal transform and improvement of going on technical scheme's the basis all should not exclude outside the protection scope of the utility model.
