De-icing requires a greater amount of power compared to water cleaning. In the design of the LCS, the mode operating at 560kHz exhibits a significantly lower impedance relative to the mode at 65kHz, making it more advantageous for generating heat and facilitating de-icing. To effectively implement the de-icing mode with the ULC1001-DRV2911EVM, it is necessary to eliminate the LC low-pass filter, as the voltage attenuation is considerably high at 560kHz.
In light of the required de-icing speed, it may be necessary to incorporate a separate heating element to achieve optimal de-icing efficiency. This recommendation arises from the relatively limited heating efficiency of piezo materials compared to other specifically designated heating alternatives.
