摘要： An AC/AC converter includes first to sixth AC switches. A series of the first and second AC switches and a series of the third and fourth switches are connected in parallel with each other between both ends of an AC input. One end of the primary winding of a transformer is connected to the node of the first and second AC switches and the other end to the node of the fourth and third AC switches. One end of the secondary winding of the transformer is connected to one end of the fifth AC switch and the other end one end of the sixth AC switch. The other ends of the fifth and sixth AC switches are connected to one of the output terminals and the mid point of the secondary winding to the other. The AC/AC converter further includes a control means which alternately operates a group of the first, third, and fifth AC switches and a group of the second, fourth, and sixth AC switches at a frequency higher than that of the input. The AC input repeatedly and alternately flows through the primary winding of the transformer in different directions at a frequency which is sufficiently higher than that of the AC input. Namely, the AC input is converted into an AC of a higher frequency. An arbitrary voltage proportional to the turn ratio of the transformer appears on the secondary side of the transformer at the higher frequency. On the secondary side, the direction of the AC is again controlled by means of the secondary-side AC switches which operate synchronously with the primary-side AC switches and the waveform of the AC closely resembles or is similar to the original waveform. Since a high frequency is impressed upon the transformer, the size of the transformer is reduced and the efficiency of the transformer is improved.

摘要： An AC voltage regulator, which not only has a fast response speed with respect to input voltage fluctuations but also is small in size and light in weight and is capable to boost an input voltage, comprises a high-frequency transformer 4, a first bi-directional semiconductor switch circuit 3, a second bidirectional semiconductor switch circuit 5 and a third bidirectional semiconductor switch circuit 6. An input AC voltage is ring-modulated by the first bi-directional semiconductor switch circuit 3 and the obtained ring-modulated voltage is transformed at a high frequency by the high-frequency transformer 4 and then demodulated by the second bi-directional semiconductor switch circuit 5. The obtained AC demodulated voltage is added to the input AC voltage to produce an AC raised voltage. This AC raised voltage is pulse width modulated by the third bi-directional semiconductor switch circuit 6, which is controlled to become ON only while the second bi-directional semiconductor switch circuit 5 is OFF, and the AC raised voltage is continuously regulated by continuous regulation of a duty ratio D of the second bi-directional semiconductor switch circuit 6 in the pulse width modulation.
