Abstract

A conversion system includes a transformer, a rectifier element, a filter circuit, a voltage regulator circuit, and a divider circuit. The voltage regulator circuit includes a first option switch, a first regulator, and a second regulator. The transformer outputs an AC voltage, and the rectifier element converts the AC voltage to a pulsating DC voltage. The filter circuit converts the pulsating DC voltage to a ripple DC voltage. The divider circuit outputs a first DC voltage of a constant positive value when the first option switch connects to the first regulator, and the divider circuit connects to the first regulator to control value of the first DC voltage value. The divider circuit outputs a second DC voltage of a constant negative value when the first option switch connects the second regulator, and the divider circuit is connected to the second regulator to control value of the second DC voltage.
