It is important because contemporary vehicles use many wireless systems like Wi-Fi which is quite vulnerable to different interference (Zankiewicz 2012). The discussed converter is controlled by 5 different control signals. High switching frequency, sufficient resolution of control and 5 different (9 total) channels impose special attention of the digital control circuit. Proper design of a power system, operating at frequencies above 300 kHz needs special attention to selection of the control strategies and their fea- sibility. When the power converter is controlled by PWM signals, a single chip microcontroller with built-in PWM block is often not sufficient, as some difficulties may occur in achieving a sufficiently high driving frequency while maintaining high enough resolution of the PWM signals (See Lewczuk et al., 2017, Wojtkowski 2017). Currently, there are relatively cheap microcontrollers available on the market, e.g. AVR family offering hardware generation of PWM signals with frequency up to 500 kHz at 7-bit resolution. In practice, such resolution may be insufficient.
