Short-circuit detection circuit, resolver-digital converter, and digital angle detection apparatus |
摘要 |
Potentials at both ends of an exciter coil to which an exciting signal is sent by a push-pull method are compared, and at least one of a short circuit to ground and a short circuit to a power supply of a signal line for the exciting signal is detected based on the duty cycle of a rectangular-wave signal indicating the result of comparison. Alternatively, a predetermined reference potential is compared with a potential of at least one of two phase detection signals before detection, and at least one of a short circuit to the ground and a short circuit to the power supply of a signal line for the at least one of the detection signals is detected based on the duty cycle of a rectangular-wave signal indicating the result of comparison. |
