Introduction to Five Types of Classic Power Supply Circuits08 March 2022
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce 5 classical power supply circuits to you. They are: power supply, switching power supply, DC-DC power supply, charging circuit and constant current source.
When Designing a Power Supply, How to Consider the Selection of Topology?07 March 2022
Hello everyone, I am Rose. Today I will tell you how to select power topology and the characteristics of each topology.
EMC can also observe the waveform with an oscilloscope?04 March 2022
What's the difference between EMC's near field and distant field? Let's talk about it together today! EMC, also known as electromagnetic compatibility, is a complete assessment of an electronic product's electromagnetic field interference (EMI) and anti-interference capabilities (EMS), and is one of the most important indicators of product quality.
Aluminum Electrolytic Capacitor Basis: Definition, Characteristics and Life03 March 2022
Hello everyone, I am Rose. Welcome to the new post today. Aluminum electrolytic capacitors are made of an aluminum cylinder as the negative electrode, which is filled with liquid electrolyte and inserted into a bent aluminum strip as the positive electrode.
How to Choose MOSFET for Switching Power Supply?02 March 2022
A metal-oxide semiconductor field-effect transistor (MOSFET) is a field-effect transistor that can be widely used in analog circuits and digital circuits.This article will help you to select MOSFET for switching power supply.
AC Contactor: What is Self-Locking?01 March 2022
AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process.This article mainly introduce the principle of AC Contactor self-locking.
AC/DC, DC/DC Converter Fundamental Guide28 February 2022
Hello everyone, I am Rose. Welcome to the new post today. This article mainly introduce the definition of AC and DC, AC/DC Converter as well as DC/DC converter.
Switching Regulator Noise: Comprehensive Understanding and Analysis26 February 2022
Switching ripple, broadband noise, and high-frequency spikes are all types of noise found in switching regulators, as described in this article. With addition, the switching regulator PSRR in relation to input noise rejection will be discussed and analyzed in this article. It is critical to have a solid grasp of switching regulator noise when building low noise switching regulators in order to minimize LDO post-regulators and enhance power converter efficiency, solution size, and design cost.
Analog-to-Digital Converters (ADCs): Decrypting Resolutions and Sampling Rates24 February 2022
Resolution and sample rate are two important factors to consider when choosing an analog-to-digital converter (ADC). To fully understand these, concepts such as quantization and the Nyquist criterion must be understood to some extent.
What is Inter-Integrated Circuit (I2C)?23 February 2022
Hello everyone, I am Rose. Today I will introduce I2C to you. The I2C bus is a simple, bidirectional two-wire synchronous serial bus developed by Philips. It requires only two wires to transfer information between devices connected to the bus.
QUIC: The Next Generation Communication Protocol22 February 2022
Hello everyone, I am Rose. Today I will introduce QUIC to you. QUIC (Quick UDP Internet Connection) is a UDP-based low-latency Internet transport layer protocol developed by Google.
Inverter Introduction: Structures, Working Principles and Features18 February 2022
Hello everyone, I am Rose. Today I will introduce inverter to you. The inverter is a converter that converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage regulation AC power (usually 220V, 50Hz sine wave).
