Power Boards

Power boards form the heart of energy-conversion systems in inverters, drives and industrial power supplies and operate at high voltages and currents. These boards typically include IGBT or MOSFET modules, rectifier diodes, thyristors, snubber circuits, Hall-effect current sensors and advanced cooling systems. Specialized diagnostics cover testing of power modules with curve tracers, inspection of gate-driver circuits, measurement of thermal losses and analysis of behavior under real load. Professional repairs include replacement of power modules with original or equivalent parts of exact specifications, reconstruction of snubber and protection circuits, replacement of current and voltage sensors, and complete dynamic testing under rated conditions. These services ensure that the power board delivers full-load capability, high efficiency and effective protection against abnormal conditions after repair.
