2. Large volume

DCDC

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

3. Complicated design scheme and rising cost

Application fields and places:

2. For remote control industrial production communication, in order to reduce the harm of potential difference and dry deflection of transmission lines, isolated Marine boost/buck voltage power supply is adopted;

high

3. For places with high safety factors, isolated power modules must be used;

4. For machines and equipment with high power quality standards, isolated Marine boost/buck voltage power supply shall be used, such as precision instruments.

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.

Non isolated Marine boost/buck voltage power supply: non isolated Marine boost/buck voltage power supply means that input and output are directly connected according to electronic components. There is no transformer difference between isolated Marine boost/buck voltage power supply and non isolated Marine boost/buck voltage power supply.
