- | 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, | ||

- | 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. | ||
