Electronic Voltage Regulation Transformer Without Mechanical Switches

The patent replaces the mechanical switch system with an electronic control system using solid-state components. The voltage regulation is achieved through electronic switching devices (such as thyristors or transistors) that control the connection between the secondary winding taps and the load, eliminating mechanical contacts and electric arcs. This substitution maintains voltage regulation functionality while eliminating contact wear and the need for frequent maintenance.

The patent extracts and removes the mechanical switch component from the voltage regulator system. By eliminating the mechanical switching mechanism, the source of electric arcs and contact wear is removed entirely. The system retains only the essential voltage regulation function through electronic means, simplifying the overall structure and reducing maintenance requirements.

The patent transforms the static, discrete tap selection mechanism into a dynamic electronic control system. Instead of fixed mechanical connections to predetermined taps, the electronic switching devices can dynamically connect any tap to the load based on real-time voltage requirements. This enables continuous or near-continuous voltage adjustment rather than limited fixed positions, while the electronic control logic manages the complexity of coordinating multiple switches.

The patent creates a universal voltage regulation system where the same electronic control architecture can achieve multiple functions: voltage boosting, voltage cutting, and continuous adjustment across a wide range. The electronic switching network can selectively connect any combination of secondary winding taps, providing versatile voltage control in a single integrated system rather than requiring separate mechanisms for different adjustment modes.

The patent replaces the arc-generating mechanical switch with an electronic switching system using solid-state devices such as thyristors or transistors. These electronic components switch currents without generating electric arcs, thereby eliminating the production of metal particles and inflammable gases. The automatic tap switching function is maintained through electronic control circuits that detect voltage conditions and activate the appropriate electronic switches to connect the desired taps.

The patent eliminates the harmful effects of electric arcs by completely replacing the arc-based switching mechanism. Rather than trying to manage or reduce arc damage, the solution converts the harmful arc discharge process into a beneficial arc-free electronic switching process. This transformation maintains the automatic switching capability while eliminating all associated harmful effects including contact erosion, gas generation, and electromagnetic interference from arcs.
