Conveter for converting code-modulated power with conversion code, power transmission system, and controller

A converter comprising:

• a terminal that receives code-modulated power into which first alternating-current, power has been code-modulated with a modulation code, the first alternating-current power having a first frequency;
• and
• a circuit that converts the code-modulated power with a conversion code to generate second alternating-current power, the conversion code being based on the modulation code, the second alternating-current power having a second frequency higher than the first frequency,
• wherein the second frequency of the second alternating-current power is N times of the first frequency of the first alternating-current power, where N is an integer greater than or equal to 2.

A controller comprising:

• a processor;
• and
• a communication circuit,
• wherein the processor:
• generates a first instruction signal for code-modulating first alternating-current power with a modulation code to generate code-modulated power, the first alternating-current power having a first frequency;
• transmits the first instruction signal to a code modulator via the communication circuit;
• generates a second instruction signal for converting the code-modulated power with a conversion code to generate second alternating-current power, the conversion code being based on the modulation code, the second alternating-current power having a second frequency higher than the first frequency;
• and
• transmits the second instruction signal to a converter via the communication circuit, and
• the code modulator and the converter are connected to each other through a transmission path.
