Analysis of the advantages and disadvantages of isolated power supply and non-isolated power supply

Analysis of the advantages and disadvantages of isolated power supply and non-isolated power supply

For commonly used power supply topologies, non-isolated power supplies mainly include: Buck, Boost, Buck-Boost, etc.; and isolated power supplies mainly include various flyback, Forward, half-bridge, LLC and other topologies. Combining commonly used isolated and non-isolated power supplies, we can i

Causes and Corrective Measures of EMC Electrical Fast Bursts Affecting Equipment

Electrical fast burst There are three reasons for the impact on equipment.( 1) The power supply of the device is directly conducted through the power supply line, resulting in excessive noise voltage on the power line of the circuit. When the interference source is injected into the live wire or the

Shorten comparative analysis time with SpeedFit design simulation software

In the process of power supply design and debugging, when we encounter problems, we should put our thoughts into the inside of the power supply, and if we are in the power control part, what should we do if we encounter such problems? solve. That is to consider the problem from the perspective of th

Discussion on motor resolver (1)

The sensor as a sensing device plays an absolute role in the control. Reminiscent of motor controller, it generally contains temperature sensor, currentvoltage sensor, and is directly related to the electric control The motor also has a position sensor, which is what we often call a resolver, or res

High Frequency Transformer Design Principles

When designing a high frequency transformer, the leakage inductance and distributed capacitance of the transformer must be minimized, because the high-frequency transformer in the switching power supply transmits a high-frequency pulse square wave signal. During the transient process of
