In the context of the current global energy transition, the utilization rate of renewable energy continues to increase. Clean energy such as solar and wind energy has become an important part of the energy structure. However, there are still challenges to the efficient conversion and storage of these renewable energy sources. VBP1254N MOSFETs were introduced by VBsemi because excellent performance and reliability were the key factors in solving these problems. High-efficiency inverter core The inverter is an important equipment that converts direct current into alternating current, and is widely used in solar power generation systems and wind power generation systems. The emergence of VBP1254N provides strong support for the efficient energy conversion of inverters. Its drain-to-source voltage (VDS) of 250V and drain-to-source current (ID) capability of 60A enable MOSFETs to handle high-power power conversion. In addition, VBP1254N uses advanced trench technology to provide low on-resistance (RDS(on)). When VGS=10V, the typical value is only 40mΩ. This feature significantly reduces energy loss, improves the conversion efficiency of the inverter, helps the system maintain low heat accumulation at high power output, and extends the life of the equipment. A reliable choice for battery management systems In renewable energy systems, battery management systems (BMS) are critical to the performance of energy storage devices. VBP1254N is a reliable choice for battery management systems due to its stable performance and high threshold voltage (Vth, 3.5V typical). MOSFETs can effectively control the current during charging and discharging to ensure the safe and efficient operation of the battery pack under different working conditions. Its ±20V gate-to-source voltage (VGS) feature enables VBP1254N to operate reliably under extreme conditions. This is particularly important for fast response and high reliability requirements in energy storage systems, ensuring that the system can quickly adjust the current under various load conditions, avoid overcharging or overdischarging the battery, and prolong the battery life. Application prospects and advantages The high performance of the VBP1254N makes it very promising for use in renewable energy systems. Whether it's an inverter or a battery management system, this MOSFET performs well. Its excellent performance in high-power energy conversion and energy storage applications perfectly overcomes the relevant technical difficulties and provides a solid guarantee for the efficiency and reliability of the energy system.

We know that push-pull circuits come in many types, such as class A or class B amplifiers. Class B amplifiers are the ones used in practical applications. They are more efficient than class A, but they are often affected by crossover distortion. So how does it affect it? How can it be reduced? When the signal is distorted at 0V, the transistor will provide a voltage of 0.7v at the base-emitter junction before turning on. When the AC input voltage is applied to the push-pull amplifier, it increases from 0 until it reaches 0.7V, and the transistor remains off without any output. So why does crossover distortion occur when VIN reaches zero? (Class B amplifier) In fact, transistors Q1 and Q2 cannot be turned on at the same time. If Q1 is turned on, VIN must be greater than Vout, and if Q2 is turned on, Vin must be less than Vout. If VIN is equal to zero, Vout must also be equal to zero. When VIN increases from zero, the output voltage Vout will also remain at zero. Until V IN is less than 0.7V, the output voltage shows a dead zone, and the same situation will occur when V IN starts to decrease from zero. How to reduce the crossover distortion of the push-pull transistor circuit? It can be corrected by using two diodes that are turned on at the transistor position, that is, the class AB amplifier circuit. It uses the characteristics of both. From 0V to 0.7V, the diode is biased in the on state to make up for the 0.7 V loss of the emitter follower. At this time, the transistor has no signal at the base, which solves the crossover distortion problem. In addition, it can also be achieved by reducing the resistance value. This is because the resistor RB1 controls the current of D1. The smaller RB1 is, the greater the current is, that is, the greater the voltage of the diode is, so when there is no input signal, the Vbe will be greater. This increased deviation will further reduce the distortion. However, the specific application situation is still based on the actual circuit design.
