 One of the limitations of the charge pump is the impossibility to obtain larger supply currents. The problem can be solved using a transformer and wiring, that will __convert__ the input DC voltage to AC. Given that the converted voltage can be of significantly higher frequency than the usual 50Hz, the size of the transformer, having the same output, can be much smaller. The higher frequency also allows to reduce the __smoothing__ capacity.  One of the limitations of the charge pump is the impossibility to obtain larger supply currents.

 +Moreover, in the case of input DC potential commuting sinusoidally on the transformer windings, the possibility of noise emission is considerably decreased compared to the conventional SMPS.
  
 +Another advantage in using the transformer is, that the output power supply can be galvanically isolated from the input power supply.
  
-Navíc v případě, že vstupní stejnosměrný potenciál je na vinutí transformátoru komutován sinusově, tak je značně potlačena možnost vyzařování rušení na rozdíl od klasického spínaného zdroje.  
- 
-Použití transformátoru navíc přináší výhodu, že výstupní napájení může být galvanicky oddělené od vstupního.
