The post investigates a simple 2 pin oscillator circuit which may be inserted between the pickup coil and the CDI unit of a vehicle for achieving an induced multi trigger input in response to each signal from the pickup coil coil, this in turn is expected to enhance the sparking ability of the CDI coil. […]
PWM
Sine wave PWM (SPWM) Circuit using Opamp
SPWM refers to Sine Wave Pulse Width Modulation which is a pulse width arrangement in which the pulses are narrower at the start, which gradually get broader at the middle, and then narrower again of the end of the arrangement. This set of pulses when implemented in an inductive application like inverter enables the output […]
PWM Motor Soft Start Circuit to Prevent High Consumption during Power Switch ON
In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]

What’s PWM, How to Measure it
PWM stands for pulse width modulation which signifies the variable nature of the pulse widths that may be generated from a particular source such as a discrete IC, MCU, or a transistorized circuit. What’s PWM In simple terms a PWM process is nothing but switching ON and OFF a supply voltage at a particular rate […]
