Technical scheme：A kind of tandem AC power supply system, including the first AC power being connected in exchange electrical circuit And first group of load, the second AC power and second group of load.
First group of AC/DC converter that first AC power includes being electrically connected with, first group of voltage detecting circuit, the One group of fictitious load control circuit and first group of bypass fictitious load.
Second group of AC/DC converter that second AC power includes being electrically connected with, second group of voltage detecting circuit, the Two groups of fictitious load control circuits and second group of bypass fictitious load.
When first group of load changes, the voltage in loop becomes where first group of voltage detecting circuit will detect Change information and be supplied to first group of described fictitious load control circuit, first group of fictitious load control circuit will automatically control described First group of bypass fictitious load break-make or resistance, and using first group of AC/DC converter input voltage regulation scope it is automatic The input voltage of AC power in loop where balancing it.
When being changed in second group of load, the voltage in loop where second group of voltage detecting circuit will detect Change information is supplied to second group of described fictitious load control circuit, and second group of fictitious load control circuit will automatically control institute The break-make or resistance for the second group of bypass fictitious load stated, and utilize the input voltage regulation scope of second group of AC/DC converter certainly The input voltage of AC power in its place loop of dynamic balancing.
So that series connection the first AC power in the loop and the second AC power remain each normal defeated Go out.
Beneficial effect：The present invention by adopting the above-described technical solution, can by using fictitious load current regulation act on, So that even any one load becomes, the relatively stable of its power input voltage can be also kept in the larger context, So that the power supply distribution of the two groups of power supplys of series connection in the loop reaches balance.The present invention completely solves the list of electrical type switch The defects of live wire electricity shortage, it is widely used in the signal light control field of smart home.
