Kickback Voltage in Transformers: Understanding and Mitigating Effects
What is Kickback Voltage?
Kickback voltage, also known as flyback or backswing voltage, is a crucial phenomenon in transformer operation. At Gowanda Electronics, we specialize in designing transformers that effectively manage kickback voltage for optimal performance and reliability.
Understanding the Kickback Voltage Mechanism
Magnetic Field Collapse
When the primary switch in a transformer circuit opens, it interrupts the current flow through the primary winding. This sudden interruption causes a rapid collapse of the magnetic field.
Voltage Induction
The collapsing magnetic field induces a voltage reversal in the transformer windings. The speed of this collapse directly correlates with the magnitude of the induced voltage.
Energy Dissipation
The transformer attempts to dissipate the energy stored in its collapsing magnetic field. Under load conditions, this energy flows into the load. However, in no-load scenarios, the transformer must find alternative ways to dissipate this energy.
Implications of Kickback Voltage
- High Voltage Generation: In no-load conditions, the transformer may generate extremely high voltages to dissipate stored energy.
- Component Stress: These high voltages can potentially damage switching elements like transistors, FETs, and SCRs.
- Core Losses: In real-world applications, the transformer induces eddy currents in its core, dissipating energy as core loss.
