A programmable power (PPSE) switching element. In preferred embodiments, the PPSE comprises a front power transistor, a main switching transistor, and optionally at least one reverse current blocking transistors (preferably MOSFETs) in series, the gate of each of which is connected to a gate driver; an inductor and shunt resistor connected in series with the transistors; a charge storage capacitor connected between ground and a junction located between the inductor and the shunt resistor; a high-speed NPN transistor, the collector of which is connected to the front power transistor and the emitter of which is connected to an output of the main switching transistor via the shunt resistor; a current measurement element in parallel to the shunt resistor; a voltage amplifier; and a high-speed MCU. |
