Reducing switching losses in a phase-modulated switch-mode amplifier |
摘要 |
A switching amplifier circuit includes a tri-state switching circuit receiving a DC voltage signal and having first electrical switches responsive to first control signals and providing a differential AC voltage waveform at a predetermined frequency alternating between a positive DC voltage, negative DC voltage and a zero voltage. The switching amplifier further includes a rectifier circuit having second electrical switches responsive to second control signals for receiving the differential AC voltage output waveform from the tri-state switching circuit and providing a desired output signal. The second control signals are applied to switch the second electrical switches only when the first electrical switches of the tri-state switching circuit are in the zero voltage state.
