Figure 1: MERUS™ amplifiers have a special power stage topology. In this design each half-bridge uses four MOSFETs (M1-M4) and the capacitor is “flying” between those to serve as an extra supply rail, resulting in a three-level output signal at the output switching node

Voices, noises, music – they are part of our lives. Sound has always been all around us. It connects us to our surroundings either we produce or just listen to them. Being an integral part of our everyday, conception and design of audio products and their environments have become more and more essential. In

1.5kW Digital Totem Pole PFC Design for Air-Conditioner Using iMOTION Digital Controller

Figure 1: Simplified hardware diagram

A lot of research focuses on bridgeless PFC in order to achieve higher system efficiency compared to traditional boost PFC. Most of the bridgeless PFC solutions suffer from EMI issues, which cause problems in applications where an  inverter stage shares the same ground. In this case, the PFC
