All of the previously shown converter circuits have only single outputs. Applications requiring multiple outputs can be
constructed by incorporating combinations of the former circuits. The converter shown above combines Figures 24 and 36 to form
a negative output inverter with a positive output doubler. Different combinations of load regulation are shown below. In
Figures 52 and 53 the positive doubler has a constant I out = 15 mA while the negative inverter has the variable load. In Figures 54
and 55 the negative inverter has the constant I out = 15 mA and the positive doubler has the variable load.
