Abstract: Disclosed is a dynamic multi-functional power controller in collocation with a primary side coil, a switching unit, and a current sensing resistor, performing a power control process. An induced current is generated by a secondary side coil coupled with the primary side coil through electromagnetic interaction with a conduction current flowing through the primary side coil, and an output power is generated to supply an external load when the induced current flows through an output rectification unit and an output filter unit. The power control process includes detecting if any abnormal state occurs, sopping a driving signal, waiting for a period of time, and then re-sending the driving signal. Thus, the present invention provides protection for various kinds of peak loading, avoids high power state when abnormal state being not resolved, and further reduces the average output power, thereby implementing power saving.

In particular, the power controller simultaneously performs active detection on load power to provide overload protection. Specifically, a load feedback signal related to a load power and a threshold load voltage representative of a preset threshold load power is compared, and a power counter representative of a calculated load power is increased by one, decreased by one, or kept without change according to the comparison result. Then, the power counter is employed to determine whether an overload abnormal event occurs.

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.
