摘要: Input-parallel output-parallel (IPOP)-connected converter systems allow the use of low-power modules for high-power applications. An IPOP topology with half-wave, daisy chain-connected rectifiers is presented which consists multiple half-bridge (HB) dc–dc modules. By utilizing a common-duty-ratio control scheme, without dedicated current-sharing controller, automatic sharing input current and load in achieved even presence differences more than 10% various module parameters. The steady-state dynamic-state performance proposed analyzed by using dc model small-signal system, respectively. It concluded that among can be realized applying scheme reducing difference transformer turn ratios, while only slightly affected substantial parameter mismatches. stability are verified Saber simulation an 800-W prototype consisting two HB under extended to any system three or modules, including full-bridge converters.
