9V Negative power supply units

Today I seeks Negative power supply units Circuit 9Volt sizes give friends. See in rows think ? circuit character resemble with positive voltage supply the other only get back to the direction of the electricity only. When use Transistor 2SC1061 or TIP31 as a result give current about 1A and Transformer must have 1Amp size with. Request have fun 9V Negative power supply units please sir.

Negative Ion Generator by 555

The design of the Negative-Ion Generator is fairly straightforward (see Fig. 1). The circuit is a high voltage generator. It contains a standard 555 timer that’s used to generate square-wave pulses. The pulses are applied to the base of the TIP120 NPN Darlington transistor. The Darlington provides sufficient current to the base of the 2N3055 power transistor to turn it on.
