The present invention relates to a control method of an inverter booster pump. More specifically, the inverter booster pump connects a plurality of pumps in parallel and at least one of the respective pumps is a relatively small flow pump. If the small flow pump reaches the predetermined upper limit of 60 Hz when the discharge flow amount of the pump is increased, the frequency is increased to the rate output limit of the pump. By contrast, the applied frequency is controlled in the reverse order to make the small flow pump drive from the rate output limit when the discharge flow amount of the pump is decreased. Accordingly, the present invention can prevent frequent activation of the pump while using the pump more efficiently to reduce the energy consumption. |
