Suspended capacitor voltage control method of five-level ANPC (Active Neutral-Point-Clamped) converter

The invention relates to a five-level ANPC (Active Neutral-Point-Clamped) converter, particularly to a suspended capacitor voltage control method of the five-level ANPC converter. The suspended capacitor voltage control method comprises the following steps of applying SHEPWM (Selective Harmonic Elimination Pulse Width Modulation) pulse waves to the five-level ANPC converter; performing real-time detection on a suspended capacitor voltage value of the five-level ANPC converter, performing comparison on the suspended capacitor voltage value and a reference value of the suspended capacitor voltage and determining whether a suspended capacitor needs to be charged or discharged; detecting whether the load current of the five-level ANPC converter is positive or negative and selecting the redundancy switch state which is suitable for the ANPC converter according to the positive or negative load current of the five-level ANPC converter and the determined charging and discharging state required by the suspended capacitor; performing charging and discharging on the suspended capacitor of the five-level ANPC converter through the selected switch state until that the variable quantity of the suspended capacitor voltage is zero within a sampling period and performing repeated detection on the suspended capacitor voltage value. According to the suspended capacitor voltage control method of the five-level ANPC converter, the appropriate redundancy switch state is selected according to the direction of the load current and the size of the suspended capacitor voltage so as to enable the suspended capacitor voltage to be fluctuated within a small range.

Liquid container and method of manufacturing the same

The liquid container has substantially rectangular parallelepiped shape having a bottom face that is situated at bottom when the liquid container is attached to the liquid consuming apparatus, and a first side face that is substantially orthogonal to the bottom face. The liquid container pertaining the second mode comprises a liquid storage portion that stores a liquid, a liquid feed portion that is situated downstream from the liquid storage portion and that feeds the liquid to the liquid consuming apparatus, and an air introduction portion that is situated upstream from the liquid storage portion and that introduces air into the liquid storage portion from an upstream side in association with feed of the liquid to the liquid consuming apparatus. The liquid storage portion includes a first liquid storage chamber having a first storage chamber bottom face situated at bottom, a first upstream opening situated along the first storage chamber bottom face, and a first downstream opening situated along the first storage chamber bottom face, a second liquid storage chamber that is situated further downstream from the first liquid storage chamber and that includes a second storage chamber bottom face situated at bottom, a second upstream opening situated along the second storage chamber bottom face, and a first downstream opening situated along the second storage chamber bottom face, and a connecting flow channel disposed between the first downstream opening and the second upstream opening so as to connect the first liquid storage chamber with the second liquid storage chamber. The first upstream opening, the first downstream opening, the second upstream opening, and the second downstream opening are juxtaposed in proximity to the bottom face of the liquid container. The first storage chamber bottom face slopes so as to be lower towards the juxtaposed first upstream opening and first downstream opening with the container attached to the liquid consuming apparatus. The second storage chamber bottom face slopes so as to be lower towards the juxtaposed second upstream opening and second downstream opening with the container attached to the liquid consuming apparatus.
