Electric power converting device

An electric power converting device adapted to be electrically connected between an alternating current (AC) power source and a load for providing an output voltage to the load, said electric power converting device comprising:

• a rectifier adapted to be electrically connected to the AC power source for receiving an AC signal from the AC power source and for converting the AC signal into a direct current (DC) signal;
• a flyback voltage converter electrically connected to said rectifier for transforming voltage of the DC signal received from said rectifier so as to output a regulated DC signal;
• and
• a non-isolated voltage regulator electrically connected to said flyback voltage converter for reducing a voltage ripple of the regulated DC signal received from said flyback voltage converter to output an output voltage, and adapted to be electrically connected to the load to provide the output voltage to the load.
