[0039] will refer to Figure 1 to 1 6 to explain the first embodiment. figure 1 The solar conditioner 1 in includes an electric power converter 3a-3d for converting a direct current output from one of the solar panels 2a-2d into a domestic alternating current and for a transmission system. Each electric power converter 3a-3d is arranged in a solar panel 2a-2d and is arranged on the back side of the panel 2a-2d.
[0040] The electric power converter 3a is connected to the input of the solar panel 2a. Similarly, the electric power converter 3b is connected to the input of the solar panel 2b, and the electric power converter 3c is connected to the input of the solar panel 2c. The electric power converter 3d is connected to the input of the solar panel 2d. The output sides of the electric power converters 3a-3d are connected in series with each other.
[0041] figure 1 It is shown that the output sides of the four electric power converters 3a-3d are connected in series with e...

[0093] Figure 17 A solar regulator according to a second embodiment is shown. The difference between the second embodiment and the above first embodiment is that only one polarity switching element is arranged in the regulator, the polarity switching element corresponds to all the voltage converting elements, and is arranged on the subsequent stage of the voltage converting elements. The regulator according to the present embodiment will be explained using the configuration of the regulator according to the second modification of the first embodiment. Specifically, the regulator according to the present embodiment includes a voltage conversion element 34 and a polarity conversion element 15 . In the explanation below, the suffixes "a" to "d" are added to the voltage conversion element 34, transistors M6-M9 and capacitor C1.
[0094] like Figure 17 As shown, the secondary side of each voltage conversion element 34a-34d is connected in series with each other. The voltage o...

[0098] Figure 19 A solar regulator according to a third embodiment is shown. The difference between the third embodiment and the above embodiments is that the polarity switching element is arranged on the subsequent stage of each voltage switching element. Furthermore, a wave-shaping element is arranged downstream of all polarity switching elements.
[0099] The voltage conversion element 14 and the polarity conversion element 15 are used in this embodiment. In the following explanation, suffixes "a" to "d" are added to the voltage conversion element 14, polarity conversion element 15, transistors M6-M9, reactor L1, capacitor C2 provided in each of the solar cell panels 2a-2d , diode D1 and node B1.
[0100] The voltage conversion elements 14a-14d and polarity conversion elements 15a-15d according to this embodiment are the same as those of the first embodiment. The voltage obtained by the series connection of the outputs of the polarity switching elements 15a-15d is full...
