This be power motor controller 12V circuit. with a signal MCU Control be high class voltage , about 3V. It can motor control turn advance or walk go backwards all right. By use power mosfet number IRF150 use apply to 100W small stump size hills. The relay 12V 2 contract , for change electronic pole gives motor. By feed a signal Reverse Rotation change a B pins of 2N3904 give it works to give the electric current to the coil relay. This circuit uses voltage 12V at current about 10A. The C1-4700uF help increase efficiency of the circuit while , feed the fire gives motor during first. The D2 use protect the electric current pulls sharply from motor harm with mosfet Q1-IRF150 get. Other detail in the circuit.

This AC to DC converter circuit is capable to convert an alternative voltage from 70 – 260 Vac into a DC voltage from 180 to 250 Vdc.
To achieve this convertion we use a rectifier MC34161 as a voltage doubler at low input voltages and as a classic rectifier at high input voltages.
MC34161 includes a reference power supply which delivers 2.54V at pin 1. The signal level applied at pin 2 is internally compared with a 1.27V voltage.
D5 zener diode, togheter with R1 and C4 provide IC’s required 12V voltage. Capacitor’s voltage of C2 and C3 must be > 250V. [...]

Here is a simple and effective circuit for driving florescent lamps from a 12 V supply.The circuit is nothing but consists of an oscillator, a MOSFET switch and a step-up transformer for driving the florescent lamp.

The IC1 TLC 555 is wired as an astable multivibrator for producing the necessary oscillations.The MOSFET Q1 is used to amplify the oscillations produced by the IC1.The out put of MOSFET is connected to the primary of the step up transformer to produce a ~400 V AC for driving the florescent lamp.
