Abstract :
High insulation multiple output switch power supply used for driving of IGBTs in medium-high voltage inverter is developed by means of a high frequency AC current source and special transformers with single-turn primary winding. The number and locations of outputs of the power supply can be arranged very easily to meet the requirements of the inverter. The isolation voltage among all outputs and input can be considerable high if the primary winding is made by high-voltage cable. Compared with other power supply used in same purpose, the proposal one has the advantage in size, weight, cost, efficiency and reliability. With the increase of voltage level and number of devices in the inverter, the proposed power supply will be more advantageous.
