Latest Patents

Rita holds a patent titled "Hold-up time extension for totem pole bridgeless power factor correction." This invention involves a power supply unit (PSU) that features a bridgeless PFC circuit with a hold-up time extension. The design includes a mechanism that detects voltage drops and switches to a first boost converter action to store energy in a PFC choke. If the voltage remains low, the PFC choke can transfer energy to a bulk capacitor, thereby increasing the operational time of an information handling system before a shutdown procedure is necessary. Additionally, if power returns, the selected switches are activated in a specific order to prevent inrush current from damaging the PSU components.
