CODE MODULATOR FOR CODE-MODULATING POWER WITH MODULATION CODE, CODE DEMODULATOR FOR CODE-DEMODULATING CODE-MODULATED POWER WITH DEMODULATION CODE, AND CONTROLLER THEREOF
A code modulator includes: a code-modulation circuit that code-modulates input power with a modulation code to generate code-modulated power which is alternating-current power; and a terminal through which the code-modulated power is transmitted, the terminal being connected to a transmission path.
