PM8 Application Field

The PM8 rectifier is a kind of high power diamond-shaped direct current (DC) diode that can be used in a variety of applications. Specifically, it is suitable for AC/DC rectifier systems, DC/DC converters, LED drivers, solar panel installations and Uninterrupted Power Supply (UPS) systems. Its various applications and practical uses have made it one of the most popular rectifier diodes on the market.

PM8 Working Principle

The PM8 rectifier works by producing a pulsating DC from an AC source. The rectifier is connected in series between the AC source and the load, such as a battery, that supplies voltage to an LED or DC/DC power supply circuit. The rectifier converts the AC current into a one-way current, allowing it to move through the load. This is done by forming an electric field within the diode, which only allows a current to flow in one direction.

The electric field is created by two electrical components inside the diode. The first is a semiconductor material, which is a substance that is neither completely a conductor or a semiconductor. The second is a voltage-dependent resistor, also known as a varistor, which has a different resistance depending on the voltage that is applied to it. When the voltage is greater than the voltage of the varistor, the field within the diode is too strong, preventing any current from flowing. When the voltage is less than the voltage of the varistor, the field is not strong enough and current flows freely.

The PM8 includes two diodes that are connected in a bridge configuration. This means that current can only flow through one side of the bridge at any given time. The diodes are connected in opposite directions, which allows a single current to flow through one side of the bridge and then to reverse direction when the other side of the bridge is triggered. This alternating current (AC) is then rectified, resulting in a DC output. This is known as full-wave bridge rectification.

The PM8 also has a higher surge current when compared to other standard rectifiers. This is due to the use of a special alloy material within the diode, which significantly increases its surge current rating. This can be advantageous in applications that require high start-up current, such as motor starters, electronic ballasts and air conditioner systems. Additionally, the PM8 features low power losses and a low forward voltage drop, making it highly efficient.

The PM8 is found in a wide range of consumer and industrial devices, such as electrical motors, power supplies and battery chargers. It is an ideal choice for applications where quick and accurate rectification is required, as its low forward voltage drop and high surge current rating make it a reliable and efficient device. Additionally, its ability to stand up to harsh conditions makes it suitable for use in a variety of environments. Therefore, the PM8 is an excellent choice for a variety of applications.
