在设计中，以TL 494作为PWM产生电路输出控制信号，控制开关管的导通状况，在半桥反激式输出的基础上实现了电源的多路输出。

In the design, to produce circuit TL494 as a PWM output control signals, control of the on-switch situation, the half-bridge flyback output on the basis of the power of multi-output.

仰卧的后弯体式：例如桥式，轮式，反台式，这些后弯的程度会更深，并且比俯卧的后弯带来更多强烈的感受。

Supine backbends: such as bridge pose, upward-facing bow, viparita dandasana are deeper back bends and create more intense sensations and experience than prone backbends.
