摘要： The number of switches on the primary winding side of a transformer is decreased and ripples contained in the output voltage are greatly reduced. In a state I, Sia and Sib are switched ON, in a state II, Sim and Sia are switched ON, in a state III, Sia and Sib are switched ON, and in a state IV, Sim and Sib are switched ON. As a result, in the states I to III, a transformer Trsa is connected to a capacitor Ci, in the state IV, the transformer Trsa is connected to an input power source Vi supplying an electric current in the direction opposite to that of the capacitor Ci. Further, in states I, III, and IV, the transformer Trsb is connected to the capacitor Ci, and in state II, the transformer Trsb is connected to the input power source Vi supplying an electric current in the direction opposite to that of the capacitor Ci. Further, in states I to III, the electric current generated on the secondary winding side of the transformer Trsa is supplied by a rectifying diode Doa to a load R, and in states I, III, and IV, the electric current generated on the secondary winding side of the transformer Trsb is supplied by a rectifying diode Dob to the load R.

摘要： A non-contact electrical power transmission system is capable of providing a large supply current of uniform level at an optimum transmission efficiency. The system includes a power circuit including a power supply of providing a high frequency voltage across a power winding, and a load circuit for energizing a load. The load circuit is composed of a secondary winding, a matching capacitor, a rectifier, and a choke coil. The secondary winding is magnetically coupled to the power winding so as to generate an induced high frequency voltage and to provide a leakage inductance to the load circuit. The matching capacitor is connected across the secondary winding to be cooperative with the leakage inductance and with the secondary winding to form an oscillatory circuit which provides an oscillating voltage across the matching capacitor for generating a supply current being fed through the rectifier and the choke coil to the load. The matching capacitor is selected to have a specific capacitance such that the oscillating voltage reaches its extreme each time the inducted high frequency voltage reverses its polarity. The choke coil is connected in circuit to smoothen the supply current. Thus, the supply current of uniform level can be fed to the load, reducing a possibility of incurring a noise on the supply current, yet minimizing an impedance between the supply circuit and the load circuit for realizing an optimum efficiency of converting the high frequency voltage into the supply current.

摘要： An AC voltage regulator includes an output voltage sensing and regulating device having a suitable filter characteristic to attenuate AC components therein occurring in the frequency ranges corresponding to the almost periodic oscillations or abnormal oscillations, or high frequency components of distorted waves which appear in the AC output voltage and are causes for such abnormal oscillations. The AC voltage regulator does not need to use a dummy load to suppress almost periodic oscillations even when the load is extremely small. The output voltage of the AC voltage regulator is free from abnormal oscillation components such as almost periodic oscillations and low frequency oscillations.
