Beschreibung
Zusammenfassung:	The invention provides a voltage ripple suppression circuit and electrical equipment, the electrical equipment comprises a direct current motor with a non-metal shell, a mainboard and a driving board, the mainboard controls the direct current motor to work through the driving board, the metal shell of the electrical equipment is connected with reference ground, and the voltage ripple suppression circuit is a suppression circuit with a capacitor assembly. The heat dissipation device is arranged between the hot ground end of the mainboard and the metal shell of the electrical equipment. The suppression circuit with the capacitor assembly is additionally arranged between the hot ground end of the mainboard and the metal shell of the electrical equipment, so that an interference signal flowing into the metal shell of the electrical equipment from the driving board of the motor flows back to the driving board through the capacitor assembly in the suppression circuit; the purpose of providing a low-impedance path f
