This schematic will be used several times to show the order of
operations and the equations to use to find the optimum power output of this circuit.
Legend: False Load = The false load is used in place of any potential true load, such as a light bulb, or heating element. It's resistance is equal to the resulting load presented after a filament, or heating element has reached it's operating temperature. As the temperature of a metal increases so does it's resistance. Where the inverse proportionate is true for a vacuum or a gas, and the higher the temperature, the lower the resulting resistance. A heating element will have a low starting resistance, and the resistance will increase with temperature until the operating temperature has been reached based upon the actual power applied. With neon bulbs, and fluorescent bulbs have starting resistances that are high, and once the operating temperature, or energy level has been achieved by the circuit the resistance of the bulb drops. The false load is utilized to simulate the reflected impedance, or inductance found as a change in inductance on the primary caused by the load on the secondary. After start up the transition states of secondary loads are ignored, and the continuous operating conditions of the circuit are emulated using an equal value of resistance in Ohms to represent the actual circuit load. |
