Nowadays, with the recent advances in battery technologies, cordless tools are gaining more popularity and many manufacturers have enhanced their series of autonomous devices with powerful instruments like circular saws and punches. However, the development of battery-operated tools is not an easy task and many challenging problems must be solved. The most significant of these are limited working time without recharging and controllability of the motor drives. As a result, tool manufacturers are substituting conventional universal motor drives with permanent magnet synchronous motor drives, which require more complicated electronics, but can provide the desired characteristics. In order to guarantee normal operation and satisfy safety standards, devices have to properly handle any possible hazardous situations. One of these situations is overheating of inverter switches, thus, the temperature of each transistor has to be monitored. This task is typically implemented using negative temperature coefficient (NTC) resistors, whereby voltage is sensed by analog to digital converter of microcontroller. This article proposes a software algorithm for temperature estimation and monitoring of each inverter switch, which allows excludes NTCs, decreasing overall costs and saving space on the printed circuit board. Proper operation of the developed technology is proven by the experimental results and safety certification according to UL60730.

Reliable motor control is important for electric vehicle applications. The control process requires accurate measurements of the current and rotor position information to establish correct motor control design, particularly in sensorless permanent magnet synchronous motor control systems. Practical issues regarding the motor control circuit, such as the effects of parasitic element behavior on the switching components in the insulated gate bipolar transistor-driven inverter, were discussed in this study. It analyzed the effects of parasitic elements that can cause the ringing of switching losses and affect the spike of the signal in the motor current, which must be avoided in the implementation of motor control. The gate driver circuit topology was improved to reduce this effect in motor control devices. The proposed gate driver circuit design with the ringing suppression circuit configuration achieved good performance by keeping the signal spike at less than 10% in the motor current. Furthermore, a signal spike or noise was not observed in the estimation results of rotor position when using current information as the parameter control process. Both conditions were verified by experiments on the designed motor control devices. Under these conditions, signal precision can be achieved in motor control.
