Abstract
A voltage regulation and speed regulation control circuit (100, 130, 200, 250) of an air pump (102) is provided. The voltage regulation and speed regulation control circuit (100, 130, 200, 250) may comprise a chopper power supply circuit (104, 202), a full bridge rectifier circuit (106, 204) and a switch (108, 212). The switch (108, 212) may be used to switch the chopper power supply circuit (104, 202) or the full bridge rectifier circuit (106, 204) to be connected to the positive and negative input terminals (103, 105) of the air pump (102). The output voltage of the chopper power supply circuit (104, 202) and the output voltage of the full bridge rectifier circuit may be different (106, 204).
