Topic 7 Designing a Digital Telecom Rectifier
نویسنده
چکیده
The design of a 1000-W universal AC input to 48-VDC output power supply is described. This power supply consists of an interleaved Power Factor Correction (PFC) stage and a phase shifted full bridge (PSFB) DC/DC converter, all controlled by a single UCD9501 DSP controller. The design steps leading to the development of the control effort for the DSP are outlined and compared to the equivalent steps for an analog design. The full bridge DC/DC converter serves as an instructive example of implementing a digital design, and allows comparing and contrasting with a conventional analog design.

After giving a summary of investigated passive and active schemes to mitigate common mode problems a modeling approach for the common mode voltage (CM voltage) is presented for three-level rectifiers. A novel Active Commonmode Voltage Cancellation (ACC) scheme is proposed, utilizing the reconstructed CM voltage to derive a simpler driving scheme as presented by previous contributions. The ACC s...

system the time constant of which is mainly related to the dumping resistance of the RLC series branch in the equivalent circuit. A second pole is introduced by the rectifier [6], so the whole system could be approximated by a two pole transfer function. Note that the PWM modulator moves the negative slope edge of the input voltage signal changing the duty cycle and consequently the amplitude o...
