High frequency excitation system |
摘要 |
A power module is adapted to be connected to a voltage source and to supply power to a load. The power module includes a switching bridge that includes a first power transistor and a second power transistor, a first gate controller for driving the first power transistor and a second gate controller for driving the second power transistor. The first gate controller includes a first gate transformer, and a leakage inductance of the first gate transformer forms a resonant circuit with an input capacitance of the first power transistor. The second gate controller includes a second gate transformer, and a leakage inductance of the second gate transformer forms a resonant circuit with an input capacitance of the second power transistor.
