As shown in fig. 1-3, a high-low frequency combined power supply device includes a high-frequency power supply 1 and at least one combined power terminal device 2, where the high-frequency power supply 1 and the combined power terminal device 2 are connected in parallel in the same 50/60HZ power frequency loop, the high-frequency power supply 1 modulates a high-power high-frequency cyclic power supply signal on the 50/60HZ power frequency power supply loop, demodulates and separates the high-frequency cyclic power supply and the 50/60HZ power frequency power supply through the combined power terminal device 2, and provides power for the high-frequency power loop 21 and the 50/60HZ low-frequency power loop 22 in the combined power terminal device 2.
The high-frequency power supply 1 comprises a high-frequency oscillator 11, a high-power modulator 12 and a transmitting coupling circuit 13, wherein the high-frequency oscillator 11 is electrically connected with the input end of a high-power high-frequency electronic switching device 121 in the high-power modulator 12, and the output end of the high-power high-frequency electronic switching device 121 is electrically connected with the transmitting coupling circuit 13. The high-frequency oscillator 11 provides a high-frequency driving signal for the high-power modulator 12, the high-power high-frequency electronic switching device 121 in the high-power modulator 12 modulates 50/60HZ power frequency power supply, and the modulated high-frequency power supply signal is coupled into a 50/60HZ power frequency power supply loop through the transmitting coupling circuit 13.
The composite power consumption terminal device 2 comprises a high-frequency power consumption loop 21 and a low-frequency power consumption loop 22, wherein the high-frequency power consumption loop 21 is connected with the low-frequency power consumption loop 22 in parallel, and is connected into the 50/60HZ power frequency loop through the low-frequency power consumption loop 22.
The high-frequency circuit 21 includes a receiving coupling circuit 211, a demodulation filter circuit 212, and a rectifying/voltage stabilizing circuit 213. The input end of the receiving coupling circuit 211 is electrically connected to the low frequency circuit 22, the output end of the receiving coupling circuit 211 is electrically connected to the demodulation filter circuit 212, and the demodulation filter circuit 212 is electrically connected to the input end of the rectification voltage stabilizing circuit 213. The receiving coupling circuit 211 extracts the high frequency power signal, and provides the dc working power for the loop controller 221 after passing through the demodulation filter circuit 212 and the rectification voltage regulator circuit 213.
The low-frequency power circuit 22 includes a circuit controller 221 and an 50/60HZ commercial power load 222, the circuit controller 221 and the 50/60HZ commercial power load 222 are connected in series in a 50/60HZ commercial power circuit, the high-frequency power circuit 21 is connected in parallel with the circuit controller 221 and a combination of the high-frequency chokes 223 connected in series, and the high-frequency power signal bypasses to the high-frequency power circuit 21 through a driving power supply 2221 of the 50/60HZ commercial power load 222. The output end of the rectifying and voltage stabilizing circuit 213 is electrically connected to the loop controller 221 and provides dc power.
The high-power high-frequency electronic switching device 121 in the high-power modulator 12 is a MOS transistor or an IGBT.
50/60HZ power frequency electric load 222 in the low-frequency electric loop 22 comprises a direct current electric device with 50/60HZ power frequency AC/DC driving power supply, such as an LED lamp 2222, an energy-saving lamp, a fluorescent lamp and a direct current motor.
Referring to fig. 4, in an application case of a single-hot-wire intelligent switch, the high-frequency power utilization loop 21 provides power for the loop controller 221, the loop controller 221 includes a processor 2211 and a relay 2212, and the processor 2211 performs switch control on the relay 2212. When the processor 2211 controls the relay 2212 to be conducted, 50/60HZ power frequency current forms a loop with the LED driving power supply 2221 through the high-frequency choke 223, and since the high-frequency choke 223 presents a low-resistance state to the power frequency, which is equivalent to a short circuit, the LED driving power supply 2221 generates a driving voltage to turn on the LED light emitting tube 2222, and meanwhile, since the high-frequency choke 223 presents a high-resistance state to the high frequency, the high-frequency power circuit 21 obtains a high-frequency power signal through the high-frequency choke 223 to provide power supply for the loop controller 221.
When the processor 2211 controls the relay 2212 to be open, the low-frequency electric loop 22 is open, the LED lamp 2222 is cut off, and the high-frequency electric loop 21 connected in parallel with the loop controller 221 and the combination of the high-frequency choke 223 connected in series can continuously obtain a high-frequency power signal to maintain power supply to the loop controller 221, so that the loop controller 221 can always keep a continuous working state no matter whether the LED tube 2222 is open or closed.
The high frequency power signal establishes a high frequency signal channel with the high frequency electric circuit 21 through the bypass of the LED driving power 2221, and at this time, since the signal amplitude of the high frequency power is much lower than the power frequency voltage of 50/60Hz, the dc voltage value output by the LED driving power 2221 is an ultra-low voltage which is much lower than the operating voltage of the LED lighting tube 2222, and the LED lighting tube 2222 is in an off state and cannot be turned on by conduction, so that the LED lighting tube 2222 does not flicker or turn on for a long time even in the presence of long-term low voltage power supply.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
