Abstract: The present application discloses trapezoidal fire pulse generating methods and devices. According to the devices and methods of the present application, the voltage value of the positive DC control voltage signal, the voltage value of the negative DC control voltage signal, the voltage value of the rise-time DC control voltage signal and a fall-time DC control voltage signal can be determined according to the parameter values of a trapezoidal fire pulse required to be output. Thus, corresponding DC control voltage signals can be generated. Further, the positive DC control voltage signal and the negative DC control voltage signal can be modulated to a square-wave pulse. Then, the rise-time DC control voltage signal, the fall-time DC control voltage signal and the square-wave pulse can be input to a inverse integrator so as to generate a trapezoidal fire pulse. Since there are specific quantitative relations between the rise time and fall time of the trapezoidal fire pulse and the voltage values of the rise-time and fall-time DC control voltage signals, the corresponding rise time and fall time of the trapezoidal fire pulses can be accurately controlled and adjusted so that the output trapezoidal fire pulses can be more stable and accurate.

Abstract: A trapezoid signal generating circuit has a charging and discharging circuit for a capacitor to generate a trapezoid signal which has less change at its rising portion and falling portion. Current output circuits supply a charging current and a discharging current in accordance with a voltage outputted from a current control circuit, respectively. The current control circuit has a charging and discharging circuit similar to the charging and discharging circuit, and produces an output voltage. This voltage increases in accordance with a linear function for a period from a time point when an input signal changes its level to a time point when the voltage reaches a reference voltage, and decreases thereafter in accordance with a linear function. The current flowing into the capacitor also increases and decreases in accordance with the linear function, so that the terminal voltage of the capacitor increases and decreases in accordance with a quadratic function.

Abstract: A current control circuit controls a gate potential of a transistor to equalize a load current IL with a trapezoidal wave signal Sb. The trapezoidal wave signal Sb increases at a constant gradient when a drive command signal Sa turns into H level. Due to increase of load current IL, the transistor starts operating in a linear region and a gate voltage VGS abruptly increases. A saturation state detecting circuit turns a current saturation signal Sc into L level when the gate voltage VGS exceeds a reference voltage Vr. A trapezoidal wave generating circuit stops increase of trapezoidal wave signal Sb. When drive command signal Sa turns into L level, the trapezoidal wave signal Sb decreases at a constant gradient. The load current IL decreases according to reduction of trapezoidal wave signal Sb.

Abstract: An error amplifier receives an on/off signal and supplies an error signal to an integrator. The latter provides a ramp output, which is fed back to the error amplifier whereby the error signal therefrom further is dependent upon the ramp output. The error signal is selectively clamped positively and negatively whereby the resulting ramp output has a constant ramp time, with no ramp on/off delay.
