Webthe two previous topologies is the Flyback with Active Clamp ([4] and [5]), see figure 3. The two most important advantages are: 1. Active clamp circuit allows magnetizing current to be negative, hence DCM is avoided and the output voltage is regulated even under no load conditions. 2. ZVS can be achieved with a proper design. WebJan 29, 2024 · Adopting active clamp flyback (ACF) gets you to ~450 kHz, enabling a lower profile RM8LP transformer. And finally, replacing silicon junction (SJ) FETs with gallium nitride (GaN) enables >600 kHz switching and even smaller transformer volumes. WebApr 8, 2024 · A flyback is a simple DC-to-DC or AC-to-DC converter which consists of a transformer that stores the energy when the current is passing through the circuit and releases it when the power is removed. A flyback topology was chosen, keeping in mind its characteristics, to be used for both step-up and step-down operations. dutch foods online
