Controlling Device of power for slippery ways

NOVELTY – The device has two operational amplifiers (A01, A02) whose function matches impedance between a circuit of power signals and a control circuit sliding mode. A mesh casket includes four resistors (R1-R4) that are connected to a third operational amplifier (A03). A capacitor (C1) of the two operational amplifiers calculates power error. Zeners diodes, three resistors (R11-R13) and an operational amplifier are connected with each other, and another capacitor (C2) calculates function of a proportional integral controller (6). USE – Power controller device. ADVANTAGE – The device reduces the error signal and changes the value of the drive keys shutdown angle to ensure that the power generated is equal to the reference power. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are also included for the following: (1) a direct current control system for generating wind power (2) a bus voltage control system for electric vehicles. DESCRIPTION OF DRAWING(S) – The drawing shows a circuit diagram of a power controller device. Operational amplifiers (A01-A03) Capacitors (C1, C2) Resistors (R1-R4, R11-R13) Block for promoting impedance matching (1) Proportional integral controller (6)
