Latest Patents

Richard Verreau holds a patent for a boost topology having an auxiliary winding on the snubber inductor. This invention discloses a boost converter topology that includes a resonant network comprising a snubber inductive element. The primary winding of this element is connected in series to a first resonant diode, which is linked to two additional series-connected resonant diodes at a first node. The secondary winding is coupled to a fourth resonant diode connected to the first node. This invention significantly reduces the energy stored in the parasitic capacitor of the first resonant diode by a factor of four during the turn-off of the main control switch. This reduction is achieved by allowing only a small amount of energy transfer to the snubber inductive element, preventing the two additional resonant diodes from turning on before the auxiliary switch is activated. This innovative design reduces losses and electromagnetic interference associated with the activation of the auxiliary switch.
