A numerical-analytical iterative method for solving an electrical oscillator equation

Self-excited oscillation problem occurring from a triode electrical circuit has been modelled by van der Pol. Until now, the exact solution to Pol equation is not available. This paper focuses on finding new method for solving simply and accurately. There exists several approximate iterative methods available in literature equation, such as, successive approximation method. The simple, but inaccurate large time values. In this paper, we propose variant of numerical-analytical method, which simple accurate, equation. Our solves its equivalent system first order ordinary differential equations. strategy leads implementation multistage way. Furthermore, computational experiments show that our proposed accurate sizes domain
