Investigation of temperature variations on a Class-E inverter and proposing a compensation circuit to prevent harmful effects on biomedical implants

Design block diagram and design specification

The proposed block diagram of a WPT used in biomedical implants is shown in Fig. 2. Due to the high efficiency of switching inverters, they are used in the wireless power supply system in the power transmitter part. In wireless implants, the transmitter induces the required power into the implant circuit with an inductive couple that transmits the power through the coils. In the receiver part of the body, a rectifier and a regulator are utilized to create the required power. The presented circuit of a WPT is shown in Fig. 3.
