Abstract
Helical magnetocumulative generators (MCGs) fed from explosive piezo generators (EPGs) are the most compact power supplies with an output energy of 1–10 kJ. EPGs are successfully coupled with MCGs in the operation mode and in structural parameters; these generators are easy to operate and do not require transformers or commutators. We report on the results of designing an autonomous small-size power supply based on EPGs and MCGs. Owing to bidirectional impact loading of the piezoceramic block of an EPG, the energy at the piezo generator output attains values of ∼25 J and is transferred to the helical MCG with an initial inductance of ∼1000 μH. The power supply is constructed in the form of a monoblock with a volume of ∼2 dm3 or in the form of two separate devices connected by a high-voltage cable.
