 INVERTERS An inverter is a power electronic device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and “frequency” with the use of appropriate transformers, switching, and control circuits.        Inverters are usually used to supply AC power from DC sources such as solar panels or batteries. It will be useful for emergency electric source   HOW INVERTERS WORK DC power, from a hybrid battery for example, is fed to the primary winding in a transformer within the inverter housing. Through an electronic switch (generally a set of semiconductor transistors), the direction of the flow of current is continuously and regular broken (the electrical charge travels into the primary winding, then abruptly reverses and flows back out).          Output Signal According to output voltage form they could be rectangle, trapezoid or sine shaped. The most expensive, yet at the same time the best quality inverters, output voltage in s

  How Gear Box Works  The input shaft is driven from the engine or 'power head'. (This input shaft is called the driveshaft) The driveshaft has a gear connected to the bottom of it called the Pinion gear.   The pinion gear is always in constant mesh with the forward and reverse gears. Whenever the motor is running, the pinion gear is rotating the forward and reverse gears.     The Clutch Dog   Between the forward and reverse gear there is the mechanism that selects gear. This is called the Clutch Dog. The Clutch Dog has an internal spline that is in constant mesh with the propeller shaft.   Picture the Clutch Dog having a front and a back. At each end it has large, square teeth. When you select gear on the motor you move the Clutch Dog forwards and backwards along the propeller shaft.     How Gear Box Works When the Clutch Dog is moved to select gear, it engages with the same sized square teeth on the gear that is being engaged. Remember that both ou
