Abstract

A power generation system includes an input to receive a low-voltage alternating current and a number N of voltage-conversion modules coupled to the input, each electrically connected in series. Each voltage-conversion module includes a transformer configured to convert the low-voltage alternating current into a high-voltage alternating current. Each voltage-conversion module includes a multiplier configured to convert the high-voltage alternating current from the transformer into a high-voltage direct current. The multiplier includes a positive multiplier part and a negative multiplier part. The positive multiplier part and the negative multiplier part each includes a pair of input terminals connected in parallel with the transform and at least one multiplier stage comprising a single diode and a capacitor assembly. The number N is an even number between 4 and 24.

First claim

an input to receive a low-voltage alternating current;
a number N of voltage-conversion modules electrically coupled to the input, each voltage-conversion module electrically connected together and to the input in series, and each voltage-conversion module comprising:
a transformer configured to convert the low-voltage alternating current into a high-voltage alternating current; and
a multiplier configured to convert the high-voltage alternating current from the transformer into a high-voltage direct current, the multiplier comprising a positive multiplier part and a negative multiplier part, the positive multiplier part and the negative multiplier part each comprising a pair of input terminals connected in parallel with the transformer, and at least one multiplier stage comprising a single diode and a capacitor assembly;

wherein the number N is an even number between 4 and 24.

2. The power generation system of claim 1 , wherein the high-voltage alternating current output from the transformer ranges from 300 V to 5000 V.

3. The power generation system of claim 1 , wherein the high-voltage direct current output from the multiplier ranges from 1.5 kV to 40 kV.

4. The power generation system of claim 1 , wherein the diode is a surface mounted diode with a voltage rating ranging from 600 V to 10 kV.

5. The power generation system of claim 1 , wherein the capacitor assembly comprises one or more serially connected capacitors, wherein each capacitor is a surface mounted capacitor with a voltage rating ranging from 600 V to 10 kV.

6. The power generation system of claim 1 , wherein a switching frequency of the low-voltage alternating current ranges from 100 kHz to 1 MHz.

7. The power generation system of claim 1 , wherein a number of the at least one multiplier stage in each of the positive multiplier part and the negative multiplier part is between 2 and 8.

8. The power generation system of claim 1 , wherein a transformer of one of the number N of voltage-conversion modules is connected in series with the input and a transformer of another one of the number N of voltage conversion modules.
