Abstract: A step-up converter is utilized to convert a first lower input voltage to a second higher output voltage. The circuit includes a soft start capability such that ringing due to excessive voltage and current is substantially eliminated. In addition, this converter includes an overcurrent protection mechanism if a load failure or other overcurrent condition occurs.

Abstract: An adjustable near unity power factor is achieved while reducing harmonics in a switch-mode power supply by replacing the conventional diode bridge in the front end with an H-bridge driver. Two feedback loops are required, one feedback loop is used to regulate a DC bulk voltage by comparing the DC bulk voltage to a reference voltage and generating an error signal therefrom. A programmable offset is applied to the error signal for adjusting the power factor. A second feedback loop samples and scales the AC input voltage for use as a scaled replica of the input current. The actual input current is then compared to the scaled replica current to produce a second error signal. The two error signals are multiplied to determine the desired input current wherein the desired input current follows the AC input voltage. The desired input current is pulse width modulated by a fixed frequency sawtooth waveform for providing switching signals for controlling the H-bridge driver.
