What is the low ESR and high ripple current for solid state capacitors
What is the low ESR and high ripple current for solid state capacitors
Capacitors are energy storage elements used in circuits for tuning, filtering, coupling, bypass, energy conversion, and delay. Capacitors are often called capacitors. According to its structure, it can be divided into three types: fixed capacitor, semi-variable capacitor and variable capacitor. Solid aluminium electrolytic capacitor is short for conductive polymer solid aluminium electrolytic capacitor, and is one of the highest-grade products in capacitor products. ESR (Equivalent Series Resistance) refers to the series equivalent resistance, which is an important indicator of capacitance. The lower the ESR, the faster the charge and discharge of capacitance. This performance directly affects the decoupling performance of power supply circuit of microprocessor. The advantage of low ESR of solid-state electrolytic capacitance in high frequency circuit is more obvious. It can be said that the low ESR characteristics at high frequencies are the watershed between the performance differences of solid electrolytic capacitance and liquid capacitance. The ESR of solid-state aluminium electrolytic capacitance is very low, with very small energy dissipation. The very low ESR characteristic of the solid state capacitor under high temperature, high frequency and high power conditions can fully absorb the high amplitude voltage generated between the power cords in the circuit and prevent its interference to the system. Currently, the power consumption of the CPU is very large, the main frequency is far beyond 1GHz, the peak current of the CPU reaches 80A or more, and the output filter capacitance is close to the critical point of operation. On the other hand, CPUs work in a variety of modes, most of the time in the process of working mode conversion. When the CPU changes from a low power state to a full load state, the large amount of energy required for instantaneous (generally less than 5ms) switching of this CPU comes from the capacitance in the CPU power supply circuit. At this time, the high-speed charging and discharging characteristics of the solid state capacitor can output the high peak current instantaneously, ensuring adequate power supply and ensuring the stable operation of the CPU.

What method can be used to measure the output ripple and switch transient of the voltage regulator?
What method can be used to measure the output ripple and switch transient of the voltage regulator?
Voltage regulator (AVR) is specially designed for AC brushless generator with matching base wave, harmonic compound excitation or permanent magnet generator excitation (PGM system). The voltage regulator realizes the automatic adjustment of the output voltage of the generator by controlling the excitation current of the alternating current exciter of the generator. Generator voltage regulator can be used for normal 60/50Hz and mid-frequency 400Hz single-machine or parallel-running generators. It is important to minimize the output ripple and transient of the switch regulator, especially when supplying power to noise-sensitive devices such as high-resolution ADC, the output ripple will appear distinctly spurious in the ADC output spectrum. To avoid reducing signal-to-noise ratio (SNR) and stray-free dynamic range (SFDR) performance, switch regulators are usually replaced by low-pressure differential regulators (LDOs), sacrificing the high efficiency of switch regulators in exchange for cleaner LDO output. Understanding these artifacts will enable designers to successfully integrate switch regulators into more high-performance, noise-sensitive applications. Output ripple and switch transient depend on the regulator topology and the value and characteristics of external components. Output ripple is the residual AC output voltage, which is closely related to the switch operation of the regulator. Its base frequency is the same as the switch frequency of the regulator. Switch transient is a high frequency oscillation that occurs during switch switching. Their magnitude is expressed in terms of the maximum peak voltage, which is difficult to measure precisely because it is highly correlated with the test settings. The inductance and output capacitance of the regulator are the main components that affect the output ripple. Smaller inductance produces faster transient response at the expense of larger current ripple; A larger inductance makes the current ripple smaller at the expense of a slower transient response. The output ripple can be minimized by using a low effective series resistance (ESR) capacitor.

Wireless charging technology has become increasingly popular in recent years, allowing users to charge their devices without the need for traditional cables and cords. One key component of wireless charging technology is the wireless charging coil, which plays a crucial role in transferring power from the charging pad to the device being charged.So, what exactly is a wireless charging coil? In simple terms, a wireless charging coil is a coil of wire that is used to create an electromagnetic field, which is then used to transfer power wirelessly from the charging pad to the device being charged. The coil is typically made of a conductive material, such as copper or aluminum, and is wound into a specific shape to optimize its performance.The wireless charging coil works by generating an alternating current (AC) when it is placed near a charging pad that is connected to a power source. This AC current creates a magnetic field around the coil, which in turn induces a current in a second coil located in the device being charged. This induced current is then used to charge the device's battery.There are two main types of wireless charging coils: transmitter coils and receiver coils. Transmitter coils are typically larger and more powerful, as they are responsible for generating the magnetic field that transfers power to the receiver coil. Receiver coils, on the other hand, are smaller and are usually integrated into the device being charged.The design and placement of the wireless charging coil are crucial factors in determining the efficiency and effectiveness of the wireless charging system.
