Power connectors
Power connectors are specifically designed for the purpose of transferring power from one device to another or from one point to another point of a same unit. Connectors of this category generally have comparatively high voltage, current and temperature ratings. In this article, we will be discussing some of the common power connectors including IEC…
Transformerless 1-Phase Multilevel Photovoltaic Inverter
Abstract- For low-voltage dc energy sources, a power conditioning system (PCS) is needed to convert the energy sources to a higher-voltage dc before making it to ac for grid tie applications. Fuel cells and Solar photovoltaic (PV) are perhaps the most well-known and prospective energy sources with low voltage dc output. A thermoelectric generator,…
Insight – How DC Motor Works
DC Motors convert electrical energy (voltage or power source) to mechanical energy (produce rotational motion). They run on direct current. The DC motor works on the principle of Lorentz force which states that when a wire carrying current is placed in a region having magnetic field, than the wire experiences a force. This Lorentz force provides a torque to the coil to rotate.When we pass the input DC current to the coil through the brushes, it directly goes to the coil inside the motor body. This makes coil to work as an electromagnet. Magnetic fields of both magnets interact with each other that results in a force which in turn produces the necessary torque required to move the coil.
