Patent number: 11895745Abstract: A power supply may provide a constant source of DC power through a first inductor-capacitor network, across a two-line conductor, and through a second inductor-capacitor network to a remote load. A modulator at the supply may modulate a carrier frequency with an information signal containing control data and may pass a modulated signal to the load via the conductor with the DC power. At the load, a demodulator may extract the control data, and operation of the load, such as a bank of LEDs subjected to dimming, may be modified based on the control data. The inductor-capacitor networks enable decoupling of the DC power and data for simple and low-cost implementations at comparatively low frequencies. In examples, the carrier frequency is at least 10 times the rate of the information signal yet below typical communication frequencies such as 525 KHz.Type: GrantFiled: December 2, 2020Date of Patent: February 6, 2024Assignee: Viza Electronics Pte.
