POWER BOOSTER AMPLIFIER |
摘要 |
The main difference between the power booster amplifier according to this invention and state of the art class D amplifiers is in the connection of a load between a power supply and a switching half bridge which is supplied from a bridge capacitor. The switching half bridge operation is controlled by pulse-width modulated control signals. Thereby, it is possible to completely eliminate both input and output filters which are required in state of the art class D amplifiers. It is also possible to achieve several times higher power at the load due to the additional supply from the bridge capacitor for the switching half bridge. The conducted and radiated EMI noise is significantly reduced in comparison with state of the art class D amplifiers. This embodiment provides a low price, small size and low EMI noise level.
