The purchase of DCDC converter should be cautious(3)

The advent of the era of intelligence has led to more and more electrical equipment. In order to protect the reputation of the company and ensure the safety of consumers, the insulation problem must be considered when purchasing power modules. If the insulation of the power module is insufficient, it will be used for a long time. There may be leakage of electricity. Once a consumer is injured, it will have a serious impact on the brand image of the company, and it may even make a company slump and disappear from the market completely.

Drive module power supply
The frequency converter power supply is mainly used for the frequency conversion and speed regulation of the AC motor. The main circuit of the inverter power supply adopts the AC-DC-AC scheme. The power frequency power supply becomes a fixed DC voltage through a rectifier, and then a PWM high-frequency converter composed of high-power transistors or IGBTs inverts the DC voltage into an AC output with variable voltage and frequency. The output waveform of the power supply is similar to a sine wave. It is used to drive the AC asynchronous motor to realize stepless speed regulation.

DCDC converter can be bought in many places, and they are not scarce items, but it is necessary to pay attention to the flame retardant performance and insulation performance during the purchase process, so as to buy high-quality power modules and protect their own interests.
