V15P12HM3/H

Introduction

V15P12HM3/H rectifiers are the most popular single-phase rectifier devices used in many industries. These rectifiers are essential to the operation of many systems and can be used in a wide variety of applications. This article will examine the application field and working principle of the V15P12HM3/H rectifiers.

Application Fields

The V15P12HM3/H rectifiers are ideal for a variety of applications, including alternating current (AC) to direct current (DC) power conversion, DC motor control, switch-mode power supplies and general AC-to-DC rectifiers. The device can be used for high-efficiency applications and its wide operating temperature range makes it suitable for industrial and consumer applications. In addition, the device has an additional internal diode for reverse voltage protection.

The device has a wide range of outputs from 400-1000V peak and its small package size further enhances its suitability for power supply applications. The device is also well suited for AC-to-DC rectification for lighting applications and can be used for systems that require up to 1.2 kV peak.

In addition, the device is compliant with the International Electrotechnical Commission (IEC) 60601-1 standard and meets the requirements of the RoHS Directive.

Working Principle

The V15P12HM3/H rectifier works on the principle of a single-phase half-wave rectification. When supplied with an alternating current, the device blocks positive cycle, allowing the negative cycle to pass through. This means that the output of the device is a unidirectional current.

At the heart of the device is a p-type semiconductor, which is connected to the external power source. When the external voltage is positive, the p-type semiconductor turns on and allows current to flow, thus rectifying the signal. When the signal is negative, the p-type semiconductor turns off and blocks the current, thus preventing reverse currents.

The V15P12HM3/H rectifier also includes an additional diode, which is used to further protect the device from reverse voltage. This diode is set to activate when the external voltage is lower than the forward voltage of the device. This helps to ensure that the device is not damaged in the case of an over-voltage.

In addition, the device is protected by built-in thermal and current limiting protection, which helps to prevent over-current and over-temperature conditions.

Conclusion

The V15P12HM3/H rectifier is a popular single-phase rectification device and is ideal for a wide range of applications. The device is suitable for AC-to-DC rectification and DC motor control, and has an additional diode for reverse voltage protection. In addition, the device meets the requirements of the IEC 60601-1 standard and is RoHS compliant.
