Abstract
Contactless power supply systems are of high interest in small power and large power applications. Many high efficiency contactless systems use the resonant operation mode. A parallel compensation system is presented enlarging overall system safety and allowing for resonant system parameter change while maintaining zero current switching (ZCS) operation. Basics of digital control unit construction and operation are presented. Simulation and experimental results are given for control system operation. Systems performance allows for large resonant circuit parameter drift. Modern DSP control unit minimizes the necessary external circuitry and time delays in case of most important operations.

Highlights
Contactless power supply is a rapidly developing technology field, most of all in recent years
In case of constant parameter values the resonant circuit current and voltage are sinusoidal and no compensation is necessary, system operates in the resonance point (ZCS) using only states of operation given in Fig. 2(a) and Fig. 2(c)
A unique contactless, coreless power supply system was presented operating in the series resonance mode
Summary
Contactless power supply is a rapidly developing technology field, most of all in recent years. Applications covering larger powers are of highest interest because of the increase of overall convenience and safety and because of possible implementations in automotive and transportation industries [3]–[5]. These systems can be used for instance as a battery chargers [6], [7], that can deliver power during idle time of the vehicle. Proposed compensator is connected in parallel to system’s resonant capacitor Another possibility includes the use of an additional capacitor as described in [13], [14].
