Abstract
A first pattern and a second pattern are stacked with each other. In a pattern of a first circuit for high voltage, a GND is formed as a solid pattern. In a pattern of a second circuit for low voltage, a GND is formed as a solid pattern. The solid pattern of the GND of the pattern of the first circuit for high voltage and the solid pattern of the GND of the pattern of the second circuit for low voltage partially face each other, thereby improving noise-resistant performance of the circuit for high voltage.
Claims5
A voltage detection unit comprising:
- a first pattern formed with a pattern of a first circuit for high voltage and a pattern of a first circuit for low voltage;
- and
- a second pattern formed with a pattern of a second circuit for high voltage and a pattern of a second circuit for low voltage, wherein
- the first pattern and the second pattern are stacked with each other,
- in the pattern of the first circuit for high voltage, a GND is formed as a solid pattern except on parts formed with signal lines and insulating parts,
- in the pattern of the second circuit for low voltage, a GND is formed as a solid pattern except on parts formed with signal lines and insulating parts, and
- the solid pattern of the GND of the pattern of the first circuit for high voltage and the solid pattern of the GND of the pattern of the second circuit for low voltage partially face each other in a stacking direction in which the first pattern and the second pattern are stacked with each other.
