Abstract: This Research paper, contains the design and construction of a multi-action power transformer which in addition to its dual purpose of both stepping-up and stepping-down voltages, also performs sealing and cutting functions using the inductance/resistance heating principle. The multi-action power transformer is a three-in-one device that uses the principle of mutual inductance for its operation. It contains a primary winding, and two secondary windings with three outputs all depending on a common input supply to provide a step-up voltage of the range 220 V – 240 V and step-down voltages of the range 90 V – 110 V and 25 V – 50 V respectively. The device when tested with household electronic with 220V – 240V specification, functioned for all input voltages within 100 V – 180V range. Below 100V, the output was observed to be too low (< 135 V) and above 180V, the output was observed to be too high for use (>240 V). For household electronics with 110V specification, the device functioned well for input voltage range 220 V – 170V. Below 170V, the voltage was observed to be low (<85 V) and above 220 V, the output was observed to be too high (>110 V). The Sealing outlet however worked well for a wide range of voltages, 10V – 240V. The device, is highly effective for provision of standard voltages for commonly used household electrical equipment, polythene sealing for petty traders as well as provision of amplified voltage to be utilized by automatic voltage regulators.
