A novel topology with applying the concept of the embedded technique to an active switched-capacitor qZSI topology named an active switched-capacitor embedded quasi-Z source inverter (ASC-EqZSI) topology is proposed. By inserting one diode and switch to the classic qZSI and embedding a single dc voltage source at the impedance network, the proposed topology has high boost factor, and performs a reduced...
This paper proposes the topology of single-phase Z-source three-level inverter, which combines the advantages of Z-source inverter and multilevel inverter. The modified modulation technique based on alternative phase opposition disposition (APOD) method is suggested to effectively adjust the shoot-through state for boosting and to balance two series capacitor voltages of the three-level inverter....
Bases such as potassium carbonate and potassium bicarbonate (KHCO3) are essential for the elution of trapped [18F]fluoride from ion exchange cartridges and for the prevention of [18F]fluoride adsorption on the silica glass vial during the preparation of radiopharmaceuticals for positron emission tomography imaging. However, these bases promote the chemical decomposition of precursor compounds and...
