A Thyristor Rectifier is a power conversion device that efficiently converts AC to DC, offering high efficiency and excellent control over the voltage and current output. YonderH2 specializes in providing these rectifiers, ensuring precise regulation in industrial applications where power conversion is critical.

The main advantage of a thyristor rectifier is its ability to handle large power loads with minimal energy loss. A thyristor is a four-layer semiconductor device, commonly known as a silicon-controlled rectifier (SCR), that operates through different conduction modes. It features three junctions (J1, J2, and J3), where J1 and J3 are forward biased, while J2 is reverse biased in the reverse blocking mode. When a gate trigger or gate pulse is applied at the gate terminal, the device is triggered into conduction, allowing current to flow.

YonderH2’s systems provide superior current regulation, making them ideal for applications requiring phase control and precise voltage regulation. These rectifiers efficiently manage high voltage operations while ensuring protection against dv/dt failures. Additionally, in gate turn-off thyristors (GTOs), the SCR in the ON state can be actively turned off using a negative gate signal. If excessive voltage is applied, avalanche breakdown may occur, affecting device stability.

Alongside thyristor rectifiers, YonderH2 also offers IGBT rectifiers, which provide high switching efficiency, fast response times, and reduced power losses. IGBT rectifiers are particularly useful in applications demanding precise control and high-frequency switching, making them a versatile solution for modern power conversion systems.

YonderH2’s thyristor rectifiers, IGBT rectifiers, and converter transformers are used across various applications, from motor drives to DC transmission systems, offering robust solutions with advanced control for both low and high-power environments.
