SS3P4HE3/85A

Diodes - Rectifiers - Single

The SS3P4HE3/85A is a single-phase sleek rectifier, controlled by a unique soft start feature. It features an active clamp circuit topology that ensures a stable start-up and eliminates the need for input capacitors. This rectifier can handle the high inrush current and the sharp peak voltages at start up, providing efficient and effective power conversion.

Application Field:

The SS3P4HE3/85A is ideal for a broad range of applications that require efficient power conversion in finite-space restrictive environments. These include server power supply, metering solutions, enterprise power solutions, PoE solutions, automotive powertrain systems, industrial automation, robotics, and other industrial applications.

Working Principle:

The working principle of the SS3P4HE3/85A is based on active clamp circuit topology. In this topology, each of the rectifiers is powered by an independent switch. When the switch is turned on, the voltage on the drain of the rectifier is brought up to the output voltage. As the current is supplied at the output, the active clamp circuit is energized with a reference voltage. This reference voltage is compared to the voltage of the rectifier. The difference between the two voltages is used to adjust the duty cycle of the switches that ensures the rectification process. Once the voltage between the rectifiers matches the required output voltage, the power supply will remain stable until the output current is changed.

The SS3P4HE3/85A offers several advantages over standard rectifiers, such as low power loss, low heat generating and high efficiency. Additionally, it is capable of controlling the inrush current and of limiting the sharp peak voltages at start up. This enables the SS3P4HE3/85A to provide efficient, safe and reliable power conversion.
