摘要： A flyback converter with indirect estimation of primary-side voltage at the secondary-side. The converter includes a primary voltage sensing circuit coupled to the second winding of the converter and being configured to establish an output voltage when a switch of the converter is in the first state and a first diode of the converter is reversed biased, the output voltage being representative of a voltage across the primary winding.

摘要： An isolated transformer-less capacitive power supply, and methods for using the same to generate power, are disclosed. The power supply includes first and second input terminals to receive an alternating current (AC) voltage. The power supply also includes first rectifier circuitry coupled to the first and second input terminals. The first rectifier circuitry is configured to generate a first direct current (DC) voltage. The power supply also includes second rectifier circuitry, including a first capacitor and a second capacitor coupled to the first and second input terminals, respectively. The second rectifier circuitry is configured to receive the AC voltage via the first capacitor and the second capacitor and to generate a second DC voltage concurrently with the generation of the first DC voltage.
