Bi-directional field control for proportional control based generator/alternator voltage regulator |
摘要 |
An H-bridge switching topology for bi-directional field excitation to null the effects of a rotor's permanent magnets uses both a low-side and a high-side field excitation driver to control the rotor's average field current. A standard proportional control signal for generators using uni-directional field excitation is used to control an H-bridge for bi-directional field excitation. The H-bridge consists of two pair of power switches. In a preferred embodiment, the switches are n-channel MOSFETs. A drive circuit interfaces a logic block with the H-bridge in order to properly bias the power switches. |
