1 The LTC3108 uses a small standard step-up transformer to provide a complete power management solution.

2 For a step-up transformer, the output voltage is HIGHER than the input voltage.

3 This paper has presented a module-cascaded system for multi-coil direct-drive permanent magnet wind generator system with high voltage output, eliminating the grid-side step-up transformer.

4 The unit can be started with the breaker or switch opened using the generator step-up transformer as a source of off-site power.

5 Consequently if we can solve the voltage sharing of IGBT direct series connected with several assistant peripheral circuits, step-up transformer isn't necessary and the cost is also reduced.

6 DC high voltage amplifier developed using amplitude modulation includes an amplitude modulator, a power amplifier, a step-up transformer, and a linear detector.

7 Otherwise, because of the limitation of IGBT's specified voltage, we must use special step-up transformer, which is more expensive, if we put this device into high voltage power system.
