9.5    Modified P/O Luo Converters

N/O Luo converters perform the voltage conversion from positive to negative voltages using VL technique with only one switch S. This section introduces the technique to modify P/O Luo converters that can employ only one switch for all circuits. Five circuits have been introduced in the literature [14]. They are as follows:

1.  Elementary circuit

2.  Self-lift circuit

3.  Re-lift circuit

4.  Triple-lift circuit

5.  Quadruple-lift circuit

The elementary circuit is the original P/O Luo converter. We will introduce the self-lift circuit, re-lift circuit, and multiple-lift circuit in this section.

9.5.1    SELF-LIFT CIRCUIT

Self-lift circuit is shown in Figure 9.26. It is derived from the elementary circuit of the ...
