Abstract
An input voltage is converted into a higher output voltage by several voltage stages each having a series circuit with a rectifier diode, a charging capacitor, and a switchable first semiconductor switch. Each voltage stage has a switchable second semiconductor switch is connected in parallel with the rectifier diode and the charging capacitor. The rectifier diodes of adjacent voltage stages are connected in series. First, the first semiconductor switches are closed and the second semiconductor switches are opened, to charge the charging capacitors by the input voltage. Then, the first semiconductor switches are opened and the second semiconductor switches are closed, so that the individual voltages produced on the charging capacitors add up along the series-connected rectifier diodes to produce the output voltage.
