Full-bridge class D amplifier

A full-bridge class D amplifier comprising:

• a first and second half-bridge circuit, wherein each half-bridge circuit comprises:
• a high-side switch and a low-side switch connected in series between high voltage port and a low voltage port,
• a half-bridge output terminal between the high-side and low-side switch, and
• wherein the high-side switch and low-side switch of each half-bridge circuit is configured to be switched between a conducting state and a non-conducting state, at a predetermined switching frequency, based on a first and second control signal respectively, such that for each half-bridge circuit one of the high-side switch and low-side switch is in the non-conducting state when the other one of the high-side switch and low-side switch is in the conducting state, and wherein the first and second control signal are configured to drive the first and second half-bridge circuits in differential mode,
• wherein each half-bridge circuit further comprises an output terminal inductor connected between the half-bridge output terminal and ground,
• the full-bridge class D amplifier further comprising:
• a first and second coil, said first and second coil being coupled to form a common mode choke,
• wherein the half-bridge output terminal of the first half-bridge is connected to an input terminal of the first coil, and
• wherein the half-bridge output terminal of the second half-bridge is connected to an input terminal of the second coil,
• wherein each of the first and second half-bridge circuits further comprises an output terminal capacitor connected between the output inductor and ground, and
• wherein each of the first and second half-bridge circuits further comprises a snubber-circuit connected in parallel with the output capacitor.
