The present invention provides a synchronous, continuous and adjustable power supply
system. The synchronous, continuous and adjustable power supply
system comprises a rectifying circuit, a PFC circuit, a disconnecting switch power supply, a low-
noise adjustable power supply, a
synchronizing pulse generator and a
synchronizer trigger. The synchronous, continuous and adjustable power supply
system enables the
voltage outputted by the disconnecting switch power supply to be boosted and reduced via the low-
noise adjustable power supply, so that the finally outputted
voltage value is consistent with the
voltage value set by a
setter. A synchronous, continuous and adjustable power supply provided by the present invention, firstly possesses a
low noise function and an efficient, continuous and stable adjustment function, and can solve the power supply oscillation problem in the 0V-90V continuous voltage adjustment and
continuous current adjustment, secondly can realize a plurality of low-
noise power supply systems and enables the PFC circuit and the disconnecting switch power supply to be controlled synchronously, and thirdly realizes the 100 Vac-240 Vac AC commercial power input and the 0 V-90 V continuous DC adjustable voltage output.
