Latest Patents

Kruisdijk holds a patent for a voltage isolation circuit designed for a measurement channel. This circuit features an improved method of combining high-frequency (HF) and low-frequency (LF) paths. The LF path utilizes an opto-isolator to achieve voltage isolation while allowing low frequencies to pass through. Conversely, the HF path employs a transformer for voltage isolation while accommodating high frequencies. The integration of these paths at a summing node results in an isolated input signal. To ensure a flat frequency response, the cross-over frequency between the LF and HF paths is meticulously matched. Additionally, a portion of the LF path is injected into the HF path to cancel out LF components around the transition frequency, allowing for compensation of the transformer's pole frequency.
