Power amplifier employing direct current to alternating current converter topology and amplification method in hybrid

摘要

Power amplifier using current converter continues to alternating current in hybrid topology and amplification method.The present invention relates to a power amplifier hybrid formed by the combination between a locking amplifier series (symmetrical or asymmetrical multilevel inverter cells connected in a half bridge cascade) and a linear amplifier low voltage / power.The AC power source of the proposal is intended to the synthesis of arbitrary waveform voltage, allowing, for example, the emulation of the electric power with the insertion of the controlled voltage disturbances and / or frequency for testing the conformity in the electro electronic equipment u00f4nicos, as well as tests of scanning voltage and / or frequency in machinery and equipment.
