An analysis of multi-output chopper type converter

A two-output chopper converter was analyzed. The effects of the multi-output choke's leakage inductance and line inductance were investigated from the current waveform and the output voltage regulation of the secondary uncontrolled output. The feedback loop for the switching converter could be analyzed efficiently by combining the usual SPICE program and the Block Arrow Diagram method developed by the authors. To assure the correctness of the Block Arrow Diagram method, an error amplifier circuit was analyzed by both the SPICE and Block Arrow Diagram method.<
