Founded in the 1990s, Igor Electric Co., Ltd. has more than 500 products in seven categories, including lighting power supply, lighting lamps, photovoltaic power generation transformer, distribution transformer, industrial control transformer, vehicle power supply and communication power supply, which are widely used in lighting, new energy, industrial control and electric power industries.

Recently, the charging head network obtained a LED driving power supply from Igor, which is a constant current source product, with output current of 900mA, support 20-42v DC output, maximum output voltage of 54V, nominal output power of 37.8w, and can drive 7-14 series of LED lights. Let's take apart this product in detail to see how Igor's design works.

The top shell of Igor's LED driving power supply has a snap package, and the input and output interface mother base is crimped. On the whole, it is designed for future maintenance and replacement. As a kind of LED driving power supply, PFC circuit is used at the input. Generally, PFC is not used in small power switching power supply. PFC circuit can improve power factor, conversion efficiency and reduce the primary capacitance. It can be seen that Igor pays more attention to the design.

In addition, as the LED driving power supply, it is generally installed in lamps and lanterns, so the volume is small. Therefore, two patch Y capacitors are used to help the power supply realize miniaturization. The output diodes are connected in parallel for output rectification, and the circuit is simplified.
