Abstract

PURPOSE:To provide a device which makes higher voltage by converting the electric output of a solar battery into voltage. CONSTITUTION:A switch S is attached from a solar panel F to positive side, and a C-MOS inverter IC1 for converting the electricity converted from optical energy to electric energy into an AC current is attached. The converted AC current is caused to flow to a capacitor C2 through an attached coil L1, and for other direction, it is caused to flow to a capacitor C3 through the primary side of a transformer T1. The currents are united and they are connected to negative side. A reverse current blocking diode D1 is attached before the inverter. On the secondary side of the transformer is a diode bridge for rectification attached, and further is a constant voltage circuit IC2 attached so as to flow a current at a required voltage.

Description

DETAILED DESCRIPTION OF THE INVENTION Electricity obtained by converting light energy such as a solar cell into electric energy cannot be expected to have a large output, and further electricity is generated based on the electricity, and when light is applied, current is generated. It is intended to generate counter electromotive force to generate higher voltage electricity that flows. (1) As shown in the drawing, electricity of about 5V from the solar cell,
An AC output is generated by causing the current to flow through the oscillator circuit IC1, capacitors C2 and C3 are connected in series to the coil L1 and the transformer T1 which are inductive loads, and the AC currents flow toward the coil L1 and the transformer T1, respectively. (2) As shown in the drawing, the current I flowing from the solar cell through the IC1 in the direction of the coil L1 stops flowing at the same time as the charging of the capacitor C2, and is switched off. Then, the counter electromotive force I1 is generated due to the coil L1 which is an inductive load, and flows toward the transformer T1.
Further, the current charged in the capacitor C2 is discharged,
It flows toward the transformer T1. The counter electromotive force I1 flowing in the direction of the transformer T1 and the current discharged from the capacitor C2 stop flowing at the same time when the capacitor C3 is charged, and are switched off. Therefore, on the primary side of the transformer T1 which is an inductive load, a new counter electromotive force I2 is generated in a further pulled-up state and the coil L
It flows in the direction of 1. (3) As shown in the drawing, the current I flowing from the Taiyo battery through the IC1 toward the transformer T1 stops flowing at the same time when the capacitor C3 is charged, and is switched off. Then, the counter electromotive force I3 is generated by the transformer T1 and flows toward the coil L1. Further, the current charged in the capacitor C3 is discharged and flows toward the coil L1 through the transformer T1. The counter electromotive force I3 flowing in the direction of the coil L1 and the current discharged from the capacitor C3 stop flowing at the same time when the capacitor C2 is charged, and are switched off and further pulled up. A new counter electromotive force I4 is generated and flows toward the transformer T1. (4) When an alternating current passes through an inductive load and the waveform of the alternating current has a positive voltage, the switch is turned on, and when the alternating current has a negative voltage, the switch is turned off and vice versa. An electromotive force is generated, which promotes the next counter electromotive force generation. (5) When a capacitor is used instead of a switch, that is, when the switch is turned on or off, by repeating the above-described operation of generating a counter electromotive force due to an inductive load, high voltage electricity is generated. You can do it. Due to the above, (1) connecting a capacitor in series to the coil or transformer, which is an inductive load, and using that capacitor instead of the switch, that is, turning the switch on or off, Therefore, a high voltage back electromotive force can be generated and a large output can be obtained. (2) Since high-voltage electricity can be generated based on the electricity of the solar cell, the electricity can be further charged and used.

BRIEF DESCRIPTION OF THE DRAWINGS (1) A circuit as shown in the drawing is connected to a solar cell. (2) As shown in the drawing, the coil L1 and the capacitor C2 are
The transformer T1 and the capacitor C3 are connected in series. (3) The IC 1 in the drawing uses a C-MOS, but may be a TTL if it is an oscillation circuit, and uses an inverter NOT circuit, but it may be a NAND circuit or another circuit. (4) In the drawing, a current of 12 V is taken out as an example, but if the transformer T1 and the constant voltage circuit IC2 are of a standard conforming to the voltage, a current of another voltage can be used if necessary. Can be taken out in the same way. (5) If a charging battery is placed at B in the drawing, the battery can be charged. As the resistor R3, an item suitable for the voltage to be taken out is used so that a current of about 10-12 mA flows through the light emitting diode LED1 as necessary. The resistor R3 and the light emitting diode LED1 may be omitted. (6) As shown in the drawing, the current passing through the capacitors C2 and C3 may be sent to the ground (GND).
This flowing current can be used at point A. (7) The capacitors C5 and C6 in the drawing are constant voltage circuit ICs.
This is to prevent the oscillation from 2.
