要約(日本語): This paper proposes a new topology of modular cascaded linear amplifier which the circuit consists of multiple H-bridges and a dc input voltage source. The proposed amplifier is operated as an inductorless inverter with a very low noise. The proposed amplifier can balance the capacitor voltage of each cell. Moreover, the capacitor voltages are controlled to be unequal to increase the voltage level, resulting in the increase of the theoretical maximum efficiency. A simulation result is provided to verify the proper operation of the proposed amplifier.
