ABSTRACT:
A voltage converter, whose topology can be switched over between a boost converter and a SEPIC. The boost converter has ripple current compensation. As a result, the inductors used can be utilized in optimum fashion. A thyristor which is protected against breakdown triggering by a negative gate voltage is used as the changeover switch.
