Abstract: A multifunction power conversion device for dynamical detection includes an input filter unit, a transformer, a switching transistor, a driving controller, a feedback unit and an output unit. Two sensing signals from the primary and auxiliary coils of the transformer form a current sensing zero detection signal. The digital control unit of the driving controller determines if a current flowing through a secondary coil of the transformer is reduced to zero due to discharging, and further finds valley of the current of the secondary coil. The switching transistor is turned on after a preset number of the valley and then turned off by a process of current sense. Therefore, the present invention greatly reduces switching loss, increases efficiency of power conversion, and particular, enhances flexibility of application to meet actual requirements by simply updating program executed by the digital control unit.

Abstract: A power factor correction control device for dynamically sensing and boost regulation includes a rectifying unit, a transformer, a digital regulation controller, a driving element, a sensing resistor, an output diode and an output capacitor. The control device converts an AC input power into a DC output power so as to supply an external load. The transformer includes a primary coil and an auxiliary coil, the controller employs an auxiliary voltage from the auxiliary coil to calculate the current input voltage and the current output voltage to implement feedback control for the driving element. The driving element is thus turned on and off by the controller to achieve boost function such that the output voltage is greater than the input voltage. The present invention obtains the input voltage and the output voltage by calculation without any sensing resistor, thereby reducing power consumption and increasing power conversion efficiency.
