Latest Patents
Yuanhang Zhou holds a patent for a "Lossless exciting current sampling circuit for isolated converter." This invention includes first and second voltage sampling circuits and a subtraction circuit formed by an operational amplifier. The two sampling circuits sample voltages of the primary winding of an isolation transformer, with outputs fed into the subtracter. The subtracter output serves as the circuit's output. RC low-pass filters with large time constants are utilized as primary voltage sampling circuits, enabling the integration of voltage differences between the exciting inductance terminals. This design allows for lossless current sampling without the need for resistors or transformers. The current sampling result is employed for volt-second balance control, realized alongside a hold circuit and comparator that generates a control signal by comparing the sampling hold result with the current sampling result.
