The paper presents design and modulation strategy for a high bandwidth PWM-based amplifier. It consists of multiple H-bridges connected in parallel and switched sequentially. As the effective switching frequency is a multiple of the switching frequency of each single switch, the bandwidth is scaled by the number of H-bridges in parallel. The prototype presented supports a maximum number of eight H-bridges in parallel.
