Drive Isolation Transformers: Functions & Advantages

Implementing a drive isolation transformer is the best way to remedy problems associated with the use of rectifiers and motor drives, such as notching effects, harmonics, and voltage waveform distortion. Because they ensure operations involving silicon-controlled rectifiers, variable frequency motors, or adjustable speed motors run smoothly, drive isolation transformers improve productivity and safeguard other components in companies’ systems. If you’re in need of repair services for a drive isolation transformer, or another electrical device, a licensed and experienced company can provide the assistance you need to get your facility’s operations back up and running.

Role of Drive Isolation Transformers

The general purpose of drive isolation transformers is to accommodate operations involving silicon-controller rectifiers. The use of variable frequency or adjustable speed drives is becoming more prevalent due to increased cost-effectiveness and energy-efficiency. These drives use silicon-controlled rectifiers to generate direct current; however, with a drive isolation transformer, the system can short and negatively impact the equipment involved in the circuit. Silicon-controlled rectifier applications involve high levels of mechanical stress and harmonic frequency, which drive transformers are built to withstand using symmetrical taps, coil bracings, and other specialized components.

About Silicon-Controlled Rectifiers

In essence, silicon-controlled rectifiers are solid state components comprised of four layers of semiconductors. Silicon-controlled rectifiers control current by conducting it in only one direction, unlike bidirectional devices. There are three modes of operation available through silicon-controlled rectifiers, which include forward blocking mode, forward conduction mode, and reverse blocking mode. In situations that require superior control of high-powered applications, such as motor operation, silicon-controlled rectifiers are ideal. In variable frequency and adjustable speed motor drive systems, they offer ease-of-use, enhanced productivity, and reduced maintenance expenses.

Benefits of DITs

Drive transformers shoulder the mechanical stress, harmonics, and voltage distortion involved in silicon-controlled rectifier operations. For this reason, they offer a number of benefits, such as lessening notching effects in voltage supplies, and protecting the integrity of other electrical devices. By reducing harmonics and voltage waveform distortion, Brucelectric Drive Isolation Transformers create more powerful motor drive loads. Additionally, lessened voltage distortion helps to protect sensitive loads in systems, such as variable frequency motor drives, automated systems, computers, programmable logic controllers, and other components.
