An electronic circuit is provided, including, on one same substrate, an inverter branch formed by high side and low side transistors, and the drivers of the high side and the low side transistors. The drivers include logic gates configured to receive one same PWM input signal and to generate two alternated command signals sent to the high side and the low side transistors. An inverter system is also provided, including the electronic circuit and laser optocouplers configured to electrically insulate the electronic circuit of a controller delivering a pulse width modulation (PWM) input signal and a main supply electrically supplying the drivers.
