<p>VOLTAGE CONVERTER A voltage converter for boosting the voltage and/or inverting the polarity of a DC voltage source having positive and negative terminals includes at least one series circuit of a capacitor and a diode connected through the latter with one of the voltage source terminals while the other end of the series circuit is alternately connected with the positive and negative voltage source terminals through a respective switching circuit, and an output is derived from the connection point between the capacitor and diode of the series circuit. Such output may be applied, for example, through a peak-value rectifier, to one side of a load having its other side connected to the voltage source terminal opposite to that connected with the diode of the series circuit so that a voltage two times that of the source is applied to the load. If the diode of the series circuit is connected with the negative terminal of the voltage source, the polarity of the voltage applied to the load is inverted. If a second series circuit of a capacitor and diode and an associated switching circuit are combined with the first mentioned series circuit and switching circuit to provide an output of inverted polarity at the connection point between the capacitor and diode of the second series circuit, and the load is connected between such connection point of the second series circuit and the corresponding connection point of the first series circuit, then the voltage applied to the load may be three times the voltage of the source.</p> |
