Power Supply : Circuit, Different Types and Their Working· The different types of AC power supplies are designed to offer an almost stable current, and o/p voltage may change based on the load's impedance. In some cases, as the power supply is DC, a step-up transformer and an inverter may be utilized for converting it into AC power. Some sorts of AC power alteration don't use a transformer.

Transformers Supplier Philippines· According to the Business Dictionary, a transformer is a device that converts an alternating (A/C) current of a certain voltage to an alternating current of different voltage, without change of frequency, by electromagnetic induction. A 'step up' transformer receives a low voltage and converts into a higher voltage, and a 'step down' transformer does just the reverse.
