N2 - This letter proposes T-type 3-level (T-3level) half-bride inverters for audio use. Self-oscillating inverters are preferred for feedback control with a higher loop gain, which is important for reducing the total harmonic distortion plus noise of class-D amplifiers. However, a conventional self-oscillator cannot be applied to T-3level half-bride inverters. In this letter, a self-oscillation scheme for T-3level half-bridge inverters is proposed and verified by a simulation.
