    摘要： PROBLEM TO BE SOLVED: To provide a power supply device, a power receiving device, a charging system and an obstacle detection method capable of ensuring satisfactory obstacle detection sensitivity even when the obstacle is small.SOLUTION: A modulation section 202 modulates the amplitude or the phase of a test data row output from a test data row storage 201. Receiving an instruction from a determination section 204, a power control section 203 generates a power control signal for increasing the power level for the test data row every time when the power control section 203 receives a test data row. The determination section 204 determines whether the test data row output from the test data row storage 201 and a test data row output from a transmitting side receiving circuit 124 coincide with each other. The determination section 204 also stores a previous power level at which the transmission and reception of a test data row is successfully made in a state free from any obstacle to determine existence or absence of an obstacle on the basis of a relationship between the power level at which the determination results coincide and the stored power level.

    摘要： PURPOSE:To generate a modulated wave digitally by converting the pulse width modulated wave of a reference waveform into digital value indicated by truth values ''1'' and ''0'' corresponding to the level of the modulated wave, storing the digital value in a memory and reading out information in each address of the memory. CONSTITUTION:A pulse width-modulated value is divided into n bits, the truth values ''1'' and ''0'' of respective bits are successively stored in respective addresses a1-an of an ROM1 and the addresses a1-an are successively and repeatedly specified by an address specifying circuit 2 provided with a clock signal generator 4 and an address counter 5 counting up cloc signals. Thus, pulse width modulated waves are repeatedly outputted from the ROM1 and sine waves are demodulated and outputted repeatedly from an LPF3. In this device, the frequency of demodulated waves outputted from the LPF3 can be changed only by changing the frequency of clock signals inputted to the counter 5 and the modulated waves can be digitally generated from the IC circuit, so that the structure is extremely simplified.

    【解決手段】変調部２０２は、テストデータ列記憶部２０１から出力されたテストデータ列を振幅変調または位相変調し、電力制御部２０３は、判定部２０４からの指示により、テストデータ列の送信のたびに、テストデータ列の電力レベルを増加させる電力制御信号を生成する。 判定部２０４は、テストデータ列記憶部２０１から出力されたテストデータ列と、送電側受信回路１２４から出力されたテストデータ列とが一致するか否かを判定する。 また、判定部２０４は、予め障害物がない状態でテストデータ列の送受信が成功した電力レベルを記憶しており、前述した判定の結果が一致した場合の電力レベルと、記憶された電力レベルとの関係に基づいて、障害物の有無を判定する。

    摘要： PURPOSE:To obtain the amplitude modulator which suits to high integration, has a wide applicable range, and increases in precision without any adjustment by composing a means which generates an amplitude-modulated wave of a digital- analog converter which uses the voltage amplitude value of the modulated signal as an analog reference voltage and input the quantized voltage amplitude value of a carrier as a digital code. CONSTITUTION:An input signal 1 from a modulated signal input terminal P is decomposed by a vector generator F into an in-phase modulated signal 11 and an orthogonal-phase modulated signal 12, which are passed through in-phase and orthogonal-phase waveform shaping filters A1 and A2 to obtain band-limited modulated signals 21 and 22. Further, a dedicated storage circuit stored with the quantized value of the carrier supplies the in-phase amplitude voltage of the carrier as a digital code 3d1 to a digital-analog converter B1 and the orthogonal- phase amplitude voltage of the carrier as a digital code 3d2 to a digital-analog converter B2, and they are multiplied by each other and waveform-shaped by a band-pass filter C' having an adding function, thereby obtaining a phase modulated wave 4'.
